ThermogravimétrieIndex. décimale : 667.9 Revêtements et enduits Résumé : Aliphatic polyesters based on adipic or succinic acid were synthesized by polycondensation reaction to produce poly(ethylene adipate) (PEA) and poly(ethylene succinate) (PES), respectively. The prepared polyesters (PEA and PES) were modified with monoethanol amine to produce polyesteramides, namely polyethylene adipate amide (PEAA) and polyethylene succinate amide (PESA). Full characterization of PEA, PES, PEAA and PESA was achieved using thermal, spectroscopic, and gel permeation chromatography analyses. The prepared aliphatic polyesters (PEA and PES) and polyesteramides (PEAA and PESA) were evaluated as corrosion inhibitors in paint formulations. Two groups of paints were prepared with 24 paint formulations based on medium oil alkyd resin, talc, titanium dioxide, drier and the prepared polymers with different types and concentrations. All the formulations are free from any inorganic anticorrosive pigments. PEA and PEAA were incorporated in Group I formulations. Paint formulations that contain PEA are six formulations F1A, F2A, F3A, F4A, F5A and F6A in addition to F1Aa, F2Aa, F3Aa, F4Aa, F5Aa and F6Aa based on PEAA with different concentrations 0.5%, 1.5%, 2.5%, 3.5%,4.5% and 5.5%, respectively. Group II formulations contain twelve other prepared formulations F1S, F2S, F3S, F4S, F5S and F6S based on PES, in addition to F1Sa, F2Sa, F3Sa, F4Sa, F5Sa and F6Sa based on PESA with the same series of concentrations. Physical, mechanical, and chemical properties of the coated films were determined. Corrosion tests in addition to surface analysis by a scanning electron microscope were performed to study the protection efficiency of such coats on steel. It was found that the synthesized polyesteramides can protect steel from corrosion successfully in 3.5% NaCl solution depending on their adsorption on the steel surface. The extent of steel protection coated with PESA formulations was slightly higher than PEAA.

Kubelka-Munk, Théorie deLa théorie de Kubelka-Munk (du nom de Paul Kubelka et Franz Munk) décrit les propriétés d'absorption de la lumière et de diffusion de la lumière des systèmes pigmentés, tels que les peintures ou les colorants dans les tissus textiles. La théorie peut prédire à partir de mesures d'épaisseurs à deux couches comment la couleur fonctionne à d'autres épaisseurs de couche. Cela permet aux fabricants de peinture d'estimer combien de pigments ils doivent ajouter à une peinture, de sorte que la peinture est opaque à une certaine épaisseur du travail. Avec l'aide de la théorie, l'effet de couleur du mélange de deux colorants peut être prédit si les paramètres des colorants individuels sont déterminés au moyen de mesures spectroscopiques. Les résultats sont meilleurs que l'utilisation naïve du mélange de couleurs soustractif.

SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.Index. décimale : 667.9 Revêtements et enduits Résumé : A spacecraft in orbit undergoes extreme temperature cycling, space radiations, and other extreme conditions that can potentially raise the temperature of spacecraft to harmful levels. Hardware and sensitive detectors utilized in spacecrafts require that temperatures be maintained within specified ranges. Thermal control coatings (TCCs) help to maintain the thermal equilibrium of the spacecraft at a level acceptable for vital components. This is done by employing the diffused reflection of all effective ultraviolet (UV), visible (VIS), and near-IR (NIR) wavelengths of solar radiation and emitting the infrared (IR) energy. The most commonly used TCCs have utilized potassium silicate as the binder and ZnO as the pigment (Z-93), but absorption of UV light by ZnO pigment affects the ideal scheme of these TCCs. In the present study, silica-supported zinc oxide particles with different ZnO contents were synthesized as pigments for white thermal control coatings and the optimized one was selected based on the experimental determination of the optical properties of the prepared coatings. The results revealed that the optimized TCCs containing pigment with the zinc to silicon ratio of 1.91 had better reflection and emission properties in comparison with Z-93, due to the improvement in the refractive index and the dispersion quality of pigment. Then, the scattering properties (S) of the synthesized pigments and ZnO in TCC were investigated based on the reflectance data, according to the Kubelka–Munk analysis. The general trend in scattering coefficients for each formulation showed the same shape, such that with the increase in S values, the zinc to silicon ratio of pigments was raised too. Also, this trend revealed that scattering was more efficient at longer rather than shorter wavelengths. For Z-93, this trend was completely opposite. Also, S values for Z-93 in the wavelength range of 200–400 nm were around zero, while for the prepared coatings, this was not the case. Finally, the statistical nonlinear regression method was utilized to prepare a model for reflectance as a function of the zinc to silicon ratio of pigments and the wavelength of light.

PolydiméthylsiloxaneLe polydiméthylsiloxane —[O-Si(CH3)2]n—, ou poly(diméthylsiloxane) selon la nomenclature systématique, communément appelé PDMS ou diméthicone, est un polymère organominéral de la famille des siloxanes souvent présent dans les shampoings. On l'y ajoute pour augmenter le volume des cheveux mais il peut également aller boucher les pores du cuir chevelu et rendre les cheveux gras. C'est une des raisons pour lesquelles se laver les cheveux tous les jours est très déconseillé avec un shampooing contenant des silicones.
Il existe également de l'amodiméthicone, qui est un dérivé du diméthicone.
Le polydiméthylsiloxane est un additif alimentaire (E900), utilisé comme antimoussant dans les boissons (Coca-Cola BlāK).
La chaîne de poly(diméthylsiloxane) forme également la structure de base des huiles et des caoutchoucs silicones.

TributylétainIndex. décimale : 667.9 Revêtements et enduits Résumé : Biofouling is a major issue for many industries including shipping, oil, and gas and can lead to accelerated corrosion, particularly for structures and components in and around salt water. Many efforts are undertaken to lessen its impact and financial losses. One of the promising methodologies is application of antibiofouling coatings to minimize biofouling, and the best results were observed with a superhydrophobic coating. Ample literature reviews on superhydrophobic coating have shown biofouling inhibition on the surface due to high wetting angles similar to the phenomenon on a lotus leaf. The hydrophobic coating can be deposited using multiple techniques such as electroless plating, chemical vapor deposition (CVD), sol–gel, and electrodeposition. In this review, an effort has been made to encompass such experimental work under a single domain and compare the effectiveness of each coating. In addition, mechanical properties and surface characteristics such as wetting angle, surface energy, and morphology were also discussed for various types of polymeric coating. Similarly, the application of nanoparticles such as ZnO, SiO2, TiO2, and CeO2 was found to improve the substrate's mechanical properties, the durability of coatings, improvement in wear properties, adhesion, interlaminar cohesion, and increased wetting angle and above all, improve superhydrophobicity. These improvements are compared for various nanoparticle integrated coatings. In addition, other novel approaches to prevent marine biofouling by various polymer-based coatings such as superhydrophobic, foul-release, and foul-resistant coatings are discussed in this paper.

Verre -- RevêtementsIndex. décimale : 667.9 Revêtements et enduits Résumé : It is desirable to protect pristine glass surfaces from frictive damage by applied coatings and thereby maintain large proportions of the inherently high tensile strength of such glass surfaces. These protective coatings should ideally be applied to glass surfaces immediately after they are formed into their desired configuration. This ideal concept requires that lubricous coatings be able to withstand elevated temperatures with minimal degradation of their protective properties. The majority of aliphatic polymers thermally degrade at temperatures less than 250°c and thus are not useful in the present desired application. The factors which increase the thermal stability of organic polymers are discussed. Note de contenu : - Development impetus - area of application
