The present study demonstrates a superhydrophobic surface prepared by using amphiphilic block copolymers and nano silica.Amphiphilic block copolymer poly(tert-butyl methacrylate-b-4-vinylpyridine) was synthesized through RAFT(reversible addition-fragmentation chain transfer) polymerization.IR,1H NMR spectrum and GPC were utilized to characterize the chemical structures of the copolymer.The "grafting" approach was used to graft the amphiphilic block copolymer brushes of Poly(tert-butyl methacrylate-block-4-v...
