Superhydrophobic materials have attracted interest due to numerous applications in anti-icing self-cleaning, anti-fouling, anti-corrosion, etc. Especially organic-inorganic hybrid superhydrophobic materials enhance the mechanical and wetting properties of surfaces. In this study, superhydrophobic nanoparticles(SNPs) consisting of inorganic core and organic shell were synthesized using thiol-lactam initiated radical polymerization. The surface of silica was modified with hydrolysis and condensation reaction of (3-mercaptopropyl) trimethoxysilane. The modified silica particles were used as seeds in polymerization in the presence of butyrolactam. Herein, perfluorodecyl methacrylate, methyl methacrylate and butyl acrylate were used for low surface energy, good water-repellency and good adhesion. The SNPs were characterized by NMR, TGA TEM and IR. A series of SNPs were coated on glass substrates by spray and the contact angles of glass surfaces were measured with water and hexadecane. |
