Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Nature has inspired scientists to create hydrophilic and hydrophobie paint surfaces. Considerable efforts have been made over the last few decades for developing self-cleaning surfaces exhibiting high contact angles for both polar and non-polar liquids. Self-cleaning coatings are becoming a requirement as integral part of our daily life because of their utility in various applications. Self-cleaning coatings are applied to maintain interior and exterior hygiene of the building structure and also in many automotive appliances.
This paper is regarding various approaches in self-cleaning coatings like superhydrophilicity, superhydrophobicity and Omniphobicity. Nano TiO2 chemically breaks down organic dirt, adsorbed onto the surface. Dirt can be washed with water sheets due to superhydrophilicity. Superhydrophilicity is required for uniform cleaning of the surfaces. White superhydrophobic coatings impart water beading due to high contact angle which in tum keep surface clean. Omni phobie (omni: all ; phobie: repellent) due to very low surface tension value and surface morphology repel almost all types of liquids from paint surface. A broad range of applications of omniphobic coatings are : in Decorative & automotive field, permaclean cloths, anti-icing coatings for metals etc.Note de contenu : - BASICS OF SELF-CLEANING

Sol-gel, ProcédéIndex. décimale : 667.9 Revêtements et enduits Résumé : This review mainly deals with the topics of self-cleaning coatings, focuses on the materials/ingredients that have been used in applications and recent technology that aims to improve these materials. Hydrophobic and hydrophilic techniques in coatings are discussed, and the various mechanisms of self-cleaning are described and related to the properties of materials of the coatings. Although several multinational companies have released products incorporating self-cleaning coatings, there remains much potential in this field, different characterization techniques and feasibilities of material testing are also discussed and analyzed. Though several companies have commercialized a few products based on self-cleaning coating technology, much potential still remains in this field. The scope of this article orbits around hydrophobic and hydrophilic coatings, their working mechanism, fabrication techniques that enable the development of such coatings, various functions like Anti-icing, Electro wetting. Surface switch ability and the areas where self-cleaning technology can be implemented. Note de contenu : - NATURAL LEAD : Hyrophilic coatings : photocatalytic

Procédés de fabricationIndex. décimale : 667.9 Revêtements et enduits Résumé : With the development of global industry and the increase of population, the shortage of freshwater resources has become a serious global challenge to the sustainable development of human society, prompting in-depth research on advanced water-harvesting technologies. However, the existing methods have many defects, such as easy pollution, insufficient water transportation speed, low water collection efficiency, complex preparation process, expensive raw materials, and so on. Here, inspired by natural organisms, such as beetles and cactus thorns, a new patterned surface combining a superamphiphobic region and a triangular fluorosurfactant (capstone FS50)-modified hydrophilic region has been designed for efficient and rapid water collection and condensation. The superamphiphobic part has an efficient water transmission capacity. On the one hand, owing to a good hydrophilic property, the FS50-modified part efficiently collects fog droplets that are further condensed into much larger water droplets. On the other hand, many large water drops condensed on the superamphiphobic region easily roll onto the hydrophilic FS50-modified surface, and form much larger droplets when combined with the original ones. The patterned surface achieves a very large water collection rate (WCR) of 20.6 mg min−1 cm−2, which is much larger than others reported in previous papers, while it is 1.5 and 1.3 times than that of single superamphiphobic and FS50-modified surfaces. Since both the patterns show superior oil repellency, it presents good resistance to organic pollution, resulting in very superior chemical stability and recyclability. Even after water collection for 60 cycles, the patterned surface can still reach a WCR value of 18 mg min−1 cm−2. The patterned surfaces also collect acid fog, alkali fog, and hot water fog when their WCR values are 20.1, 19.8, and 20.5 mg min−1 cm−2, respectively. This work has found a new patterned superoleophobic surface for efficient water collection, which achieves robust mechanical durability and chemical stability.

Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : In this study, a simple one-step sol–gel process was applied to synthesize SiO2-based superhydrophilic antifogging coatings on glass substrates. In this process, Si(OH)4 sol was first prepared and then SiO2 nanoparticles were added to the sol to form coating solutions. The influence of both the Si(OH)4 sol and SiO2 nanoparticle contents on the coating properties was investigated. Their contents have significant effects on the coatings’ properties, including hydrophilicity and surface morphology. The water contact angle of the optimum coating is about 3.4°. Besides, as revealed by the steam test and freeze test, the optimum superhydrophilic coating demonstrates good antifogging properties and an adequate level of mechanical strength as well. Compared to other techniques used to fabricate antifogging coating on glass substrate, the sol–gel-based process developed in this study requires no expensive equipment, and the processing time is largely shortened. Thus, such technique has great potential applications in the field of coating industry. Note de contenu : - Materials
