Anti-reflective smart coatings on glasses / Praful Sanjay Dahatonde in PAINTINDIA, Vol. LXIII, N° 6 (06/2013)  

[article]  inPAINTINDIA > Vol. LXIII, N° 6 (06/2013) . - p. 62-66 Titre : Anti-reflective smart coatings on glasses Type de document : texte imprimé Auteurs : Praful Sanjay Dahatonde, Auteur Année de publication : 2013 Article en page(s) : p. 62-66 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Matériaux intelligents Polymérisation sous plasma Revêtement antireflet:Peinture antireflet Verre Index. décimale : 667.9 Revêtements et enduits Résumé : Our eyes are very complex organs. In order for our eyes to see, there must be light. Light rays reflect off of an object and enter the eye through the cornea. At the back of the eye the light is focused by the retina, and then it is converted into electric signais to be sent to the brain. Once the brain receives the signais, vision occurs. If the eye cannot properly focus an image it is said to have a refractive error. An eye doctor can determine the type of refractive error by a test cal led refraction. Correcting a refractive error is achieved by glasses, contacts or refractive surgery. A type of optical coating applied to the surface of lenses and other optical devices to reduce reflection. Anti-reflective coating (AR coating) is made of several layers of film metal oxides that are layered on the surface of the lens. Each layer is chemically engineered to block reflected light. This causes the intensity of the light reflected from the inner surface and the light reflected from the outer surface of the film to be nearly equal, canceling each other out and el iminating glare. Antireflection coatings are used to reduce reflection from surfaces. Whenever a ray of light moues from one medium to another (such as when light enters a sheet of glass alter travelling through air), some portion of the light is reflected from the surface (known as the interface) between the two media. AR was first developed to enhance and improve the view on high powered telescopes, microscopes and camera lenses. AR coating is composed of multiple layers of metal oxides applied to the front and sometimes the back surface of the lens. This layeringeffect reduces reflected light and aliows more I ight to betransmitted through the lens. What does this do for eyeglasses? First, it improves the appearance of your eyes to the outside world. AR coating makes the lenses appear almost invisible. It also vastly improves the cosmetic appearance of wearing the lenses by reducing internai reflections in the lens, making your lenses appear much thinner. Secondly, it improves the quality of your vision by reducing reflected lights. This cuts down on glare and halos around lights, and improves the quality of your vision at night and when us ing the computer in certain work environments. While AR coating is beneficial to everyone, it is found almost universally on high index lenses. High index lenses are made out of a type of plastic that can make your lenses much thinner than regular plastic lenses. However, to achieve th is thinness, sometimes the lens material can cause unwanted reflections. As a result, manufacturers who produce very high index lenses make AR a part of the complete lens price and do not separate the lens from the AR coating because they bel ieve a very high index lens should never be worn without an AR coating.

Deposition of a PMMA coating with an atmospheric pressure plasma jet / S. Van Vrekhem in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 15, N° 4 (07/2018)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 15, N° 4 (07/2018) . - p. 679-690 Titre : Deposition of a PMMA coating with an atmospheric pressure plasma jet Type de document : texte imprimé Auteurs : S. Van Vrekhem, Auteur ; R. Morent, Auteur ; N. de Geyter, Auteur Année de publication : 2018 Article en page(s) : p. 679-690 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Méthacrylate de méthyle Plasma à pression atmosphérique Un plasma à pression atmosphérique (ou plasma à PA ou plasma froid) est le nom donné à une catégorie spéciale de plasma pour lequel la pression approche celle de l’atmosphère. Le plasma à pression atmosphérique marque une nette différence avec le plasma basse et haute pression. En effet, contrairement à ces derniers aucune enceinte de traitement n'est nécessaire. Ce type de plasma peut donc être utilisé directement sur ligne de production, évitant ainsi l'utilisation de vide qui est extrêmement onéreuse. Polymérisation sous plasma Polyméthacrylate de méthyle Le poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec. Revêtements Index. décimale : 667.9 Revêtements et enduits Résumé : Atmospheric pressure plasma jet polymerization of methyl methacrylate (MMA) was performed in order to deposit a PMMA-like coating on ultrahigh molecular weight polyethylene (UHMWPE). This study is a first step in the transfer from MMA plasma polymerization experiments previously performed in a dielectric barrier discharge (DBD) reactor to a newly designed atmospheric pressure plasma jet. In this novel plasma setup, the substrate is not directly exposed to the plasma region, but placed in the plasma jet afterglow. The effect of several plasma jet process parameters on the coating properties was investigated using different surface characterization techniques such as XPS, FTIR, AFM, and OPS. Results show that the stationary deposition of PMMA-like thin films results in a radial gradient in surface chemistry, surface morphology, and coating thickness. Additionally, the coating properties were found to significantly depend on the monomer-containing gas flow rate. This observation is also confirmed by CFD modeling, which shows that the monomer-containing gas flow rate strongly influences the gas flow pattern of the plasma afterglow and therefore the final properties of the deposited PMMA-like film.

Improvement in leather surface hydrophobicity through low-pressure cold plasma polymerization / Ya-E Feng in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CIX, N° 3 (03/2014)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CIX, N° 3 (03/2014) . - p. 89-95 Titre : Improvement in leather surface hydrophobicity through low-pressure cold plasma polymerization Type de document : texte imprimé Auteurs : Ya-E Feng, Auteur ; Xuepin Liao, Auteur ; Ya-Nan Wang, Auteur ; Bi Shi, Auteur Année de publication : 2014 Article en page(s) : p. 89-95 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Cuir Hydrophobie Polymérisation sous plasma Traîtements de surface Vinyltriéthoxysilane Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Vinyltriethoxysilane (VTES) was polymerized and deposited on the surface of upholstery crust leather by using low-pressure cold plasma technology. After plasma treatment (50 W, 300 s), the initial water contact angle of the leather surface increased from 120° to 140°, showing a significantly improved hydrophobicity of leather surface. The increased hydrophobicity of leather surface could remained even the leathers were stored for 240 d. The surface morphologies of leather were characterized by Scanning Probe Microscope (SPM) and Scanning Electron Microscope (SEM). Unlike the fiber-like texture of untreated leather, a coating of VTES polymer on the plasma treated leather surface was observed by SPM. SEM and SPM images indicated that this coating film was on the surface of collagen fibers rather than the whole surface of leather, which would not reduce permeability of air and water vapor of the leather. Energy Dispersive X-ray Spectroscopy (EDS) was performed to determine the chemical composition of leather surface. The contents of Si and O increased remarkably as leather surface was covered with polymerized VTES. The X-ray Photoelectron Spectroscopy (XPS) showed that the peaks attributed to C=C bonds of VTES and C=O bonds of collagen disappeared after plasma polymerization. All these results demonstrated that VTES was polymerized and deposited on the surface of collagen fibers after plasma treatment, which resulted in a hydrophobic surface of leather.

Improving hydrophobicity on polyurethane-based synthetic leather through plasma polymerization for easy care effect / Burcak Karaguzel Kayaoglu in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 10, N° 4 (07/2013)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 10, N° 4 (07/2013) . - p. 549-588 Titre : Improving hydrophobicity on polyurethane-based synthetic leather through plasma polymerization for easy care effect Type de document : texte imprimé Auteurs : Burcak Karaguzel Kayaoglu, Auteur ; Emre Ozturk, Auteur ; F. Seniha Güner, Auteur ; Tamer Uyar, Auteur Année de publication : 2013 Article en page(s) : p. 549-588 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Angle de contact Cuir synthétique Hydrophobie Polymérisation sous plasma Polyuréthanes Surfaces -- Nettoyage Index. décimale : 667.9 Revêtements et enduits Résumé : This study reports on the deposition of a hydrophobic coating on polyurethane (PU)-based synthetic leather through a plasma polymerization method and investigates the hydrophobic behavior of the plasma-coated substrate. The silicon compound of hexamethyldisiloxane (HMDSO), inactive gas argon (Ar), and toluene were used to impart surface hydrophobicity to a PU-based substrate. Surface hydrophobicity was analyzed by water contact angle measurements. Surface hydrophobicity was increased by deposition of compositions of 100% HMDSO, 3:1 HMDSO/toluene, and 1:1 HMDSO/toluene. Optimum conditions of 40 W, 30 s plasma treatment resulted in essentially the same initial contact angle results of approximately 100° for all three treatment compositions. The initial water contact angle for untreated material was about 73°. A water droplet took 1800 s to spread out on the plasma-treated sample after it had been placed on the sample surface. An increase in plasma power also led to a decrease in contact angle, which may be attributed to oxidization of HMDSO during plasma deposition. XPS analysis showed that plasma polymerization of HMDSO/toluene compositions led to a significant increase in atomic percentage of Si compound responsible for the hydrophobic surface. The easy clean results for the treated and untreated PU-based synthetic leather samples clearly showed that the remaining stain on the plasma-polymerized sample was less than that of untreated sample. The plasma-formed coating was both hydrophobic and formed a physical barrier against water and stain.
