Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki). Textiles et tissus

Résumé : |
Superhydrophobic coatings in the recent past is gaining great deal of attention for the range of properties provided by them for applications such as anti-icing coatings, self cleaning, biomimetic engineering materials, fouling release coating etc. A typical superhydrophobic (ultra hydrophobic) surface can repel water droplets from wetting itself, and the contact angle of a water droplet resting on a superhydrophobic surface is greater than 150°, which means extremely low wet ability is achievable on superhydrophobic surfaces. Many superhydrophobic surfaces (both manmade and natural) normally exhibit micro- or nanosized roughness as well as hierarchical structure, which somehow can influence the surface's water repellence. As the research into superhydrophobic surfaces goes deeper and wider, it is becoming more important to both academic fields and industrial applications . The scope of this article orbits around superhydrophobic coating, their working mechanism, fabrication techniques that enable the development of such coatings and their application in various fields. |
