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 : The multifaceted applications of superhydrophobic surfaces arising out of their unique surface architecture have gained significant attention in the solar photovoltaic industry as it addresses the challenges in light conversion efficiency at an industrial scale due to the soiling of surfaces. Inspired by the self-cleaning properties of the lotus leaf, this review proposes the use of superhydrophobic surfaces as an effective solution for soiling mitigation in solar cell applications. The review examines various factors influencing dust settlement and evaluates existing soiling mitigation techniques. As most literature reports the insufficiency of theoretical wetting models with the controversies around its assumptions, the importance of modified models over the theoretical models is compared and highlighted. The foundations of superhydrophobic coatings including transmittance, porosity, and refractive index of coatings, thickness and surface roughness in addition to the commonly reported surface tension and surface free energy aid to focus on feasible fabrication techniques and provide improved efficiency of solar cells. Finally, the review presents a classification of durability tests to highlight the importance of durable coatings bridging the gap between the fabrication and application of superhydrophobic coatings for solar cells on an industrial scale.

Surface anti-buéeIndex. décimale : 667.9 Revêtements et enduits Résumé : Superhydrophobicity is the tendency of a surface to repel water drops. A surface is qualified as a superhydrophobic surface only if the surface possesses a high apparent contact angle (>150°), low contact angle hysteresis (<10°), low sliding angle (<5°) and high stability of Cassie model state. Efforts have been made to mimic the superhydrophobicity found in nature (for example, lotus leaf), so that artificial superhydrophobic surfaces could be prepared for a variety of applications. Due to their versatile use in many applications, such as water-resistant surfaces, antifogging surfaces, anti-icing surfaces, anticorrosion surfaces etc., many methods have been developed to fabricate them. In this article, the fundamental principles of superhydrophobicity, some of the recent works in the preparation of superhydrophobic surfaces, their potential applications, and the challenges confronted in their new applications are reviewed and discussed.

Revêtement auto-nettoyantIndex. décimale : 667.9 Revêtements et enduits Résumé : Surface that can repel both water and oily Iiquids known as omniphobic surface & Surfaces that display I iquid contact angles greater than 150° along with low contact angle hysteresis for Iiquids with both high and low surface tension values are known as superomniphobic surfaces. This includes superhydrophobic and superoleophobic phenomena. Omniphobic coating provide a surface that can repel almost ail liquids, in recent years, several strategies have been attempted to prepare omniphobic surfaces that repel both polar and non polar Iiquids.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Nanographite-zinc particles in various ratios were synthesized by high energy ball milling and dispersed in epoxy based aero grade resins for studying their microwaves absorption in the lower frequency band of 2–9 GHz using a coaxial waveguide measurement system. Morphological characterizations of the synthesized particles showed that shuttle shaped zinc is well embedded on the exfoliated nanographite particles without any agglomeration. The higher interfacial polarization of both the graphite and zinc particles contributes to the excellent electrical conductivity and hence refers it as an ideal microwave absorber in defense applications. The paint with 20% (w/v) loading of nanographite-zinc (1:1 ratio) particles is proficient in providing microwave absorption of − 18.06 dB at 8.19 GHz with a coating thickness of 1.43 mm.
