It serves many advantages to the various industries, household section, automotives and so on. Many have negative views on plastic but the fact is plastic occupies a large section in our day-to-day life. Apart from its disadvantages, it serves many good properties. Different varieties in it like amorphous, transparent, thermoplast, thermosets are good enough to occupy large application area. To improve its performance or to extend its lifespan various coatings on plastic substrates cornes into the picture. This review explains the five different types of coatings on plastics; anti-scratch coating, anti-fog coating, anti-reflection coating, peelable coating and in the last section various coatings are noted down in miscellaneous coating section. Each of the coating serves good properties along with cost efficiency and properly adhere to the substrate. These coatings increase the sign ificant properties of plastic substrates and broaden its application area.

LDHs are layered compounds composed of positive metal hydroxides and negatively charged interlayer anions. We have discussed the structures and characteristics of LDHs in this review study, as well as many processes, such as the barrier mechanism, self-healing corrosion inhibitor method, and superhydrophobic mechanism, that demonstrate how LDHs operate in anticorrosion coatings. Additionally, how the use of LDH imparts flame-retardant qualities to the coatings is covered here, along with their respective processes. LDH coatings are suitable for packaging, biomedical, water treatment, and conductive applications alone or in combination with other materials.

Gadhave, Auteur Année de publication : 2012 Article en page(s) : p. 64-70 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Chaleur -- Rayonnement et absorption Encapsulation Polymères Revêtements Transition de phase En physique, une transition de phase est une transformation du système étudié provoquée par la variation d'un paramètre extérieur particulier (température, champ magnétique...). Cette transition a lieu lorsque le paramètre atteint une valeur seuil (plancher ou plafond selon le sens de variation). La transformation est un changement des propriétés du système. Index. décimale : 667.9 Revêtements et enduits Résumé : As the demand for the energy increasing day by day but its sources are decreasing there is a need for better utilization of available energy. This can be done by storage of the available energy when it is not required and released of the same in necessary conditions. Thermal energy is one of the important form of energy. And phase change material is worked on the basis of above principles which sotres and released the thermal energy based in the form of latent heat. Inorganic, organic and eutectic type phase change materials are available. Phase change material can be incorporated into matrix by various techniques, like direct addition, microencapsulation, nanoencapsulation etc. They find application in textile, aerospace, refrigerator, building materials, air conditioners etc. The incorporation of phase change material in paint or coating has not yet been explored fully, yet it could one of the best solutions for architectural industry.

Mhaske, Auteur Année de publication : 2022 Article en page(s) : p. 717-739 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Etudes comparatives Revêtements anti-graffitis Revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits Résumé : An anti-graffiti coating (AGC) is a protective layer applied on the surface (all types including cultural heritage and metallics) to limit possible vandalism phenomena. AGCs are one of the elementary classes of coating materials, creating a barrier layer between substrate and graffiti, preventing the penetration of graffiti into the substrate and helping easy graffiti removal. AGC can be applied on porous and nonporous substrates, including concrete, mortar, stone, granite, metals, etc. AGCs are mainly classified as permanent, semi-permanent, and sacrificial. Sacrificial AGCs include waxes, polysaccharides, and polysiloxane, whereas permanent AGCs include fluorinated polymers, nanoparticles-based coating, silicon, and polyurethanes (PU). The use of hybrid polymers in AGCs containing silane or siloxane and fluoropolymers-based compounds with effective anti-graffiti (AG) properties is an introductory class in the future AGC market. Nowadays, nanotechnology is widely used in AG pretreatment. These polymer chemistries of AGCs find the application on historical walls, public places, trains, houses, etc. The present article focuses on various types of AGCs, their current market trends based on multiple chemistries, mechanisms, and their performance with the structure–property relationships.

Superamphiphobic coatings are the new advance approach of the coating which combines the advantages of above two coatings and act as oil and water repellent at the same time. Due to this combined advantage it can act as self cleaning coating, Antifingerprint coating, Anticorrosive coating, Anti-smudge coating at the same time and helps to improve the durability and service life of the substrate on which this coating is applied. The creation of this coating is based on the principle of chemical composition and surface topography. The surface can be make superamphiphobic by various methods like sol-gel coating, electrospinning in case of fiber, plasma etching in case of plastic substrate etc. Note de contenu : - INTRODUCTION : What do you mean by superamphiphobicity ? - HOW TO CREATE SUPERAMPHIPHOBIC SURFACE ? : By sol-gel method - Preparation of the fluorinated silica nanoparticle - Superamphiphobic coating with the help of candle soot - Plasma etching technique for generation of superamphiphobic surface - Electrospinning method to generate superamphiphobic surface on the fibers - Formation of superamphiphobic surface on metal substrate - Grafting of fluorinated compound - SuperamphiphobicDiblock copolymer coatings - Superamphiphobic conductive coating - Transparent superamphiphobic surface - CHARACTERIZATION OF SUPERAMPHIPHOBIC SURFACE : Contact angle measurement - Contac angle hysterisis - Rolling angle measurement - SUPERAMPHIPHOBIC COATING OR SURFACE APPLICATIONS Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=18971 [article]
