Transparent self-cleaning coatings repellent to ultralow surface tension liquids in extreme environments

Polymerization-Induced Hierarchical Hybrid Particles from Siloxane Emulsification Endowing Polyurethane Composite Coating with Superhydrophobicity, Thermal Insulation, and Fluorescence

“…The superhydrophobic coating is mainly determined by the rough structure and surface chemical compositions. − The incorporation of micron/nanoparticles is commonly used to enhance the roughness of the coating due to the particles’ inherent large specific surface area, and fluorocarbons are the most representative low-surface-energy materials. − Thus, the methods of constructing superhydrophobic coatings based on fluorocarbon-modified particles have been extensively investigated. − Jiao et al created superamphiphobic coatings by spray-coating the suspension of perfluoro-decyltrichlorosilane-modified silica nanoparticle powders and ceramic binders, which exhibited excellent liquid repellency against several low-surface-tension liquids. In addition, it is necessary to find an eco-friendly substrate with good adhesion and film-forming properties that can combine strongly with particles.…”
