The experimental results indicated that the impedance ofy-APS silane treated substratcs and the cross-linking degree of γ-APS films gradually increased with the increasing solution concentration. There was some noticeable transformation in molecular orientation and protective performance of y-APS films when solution concentration was above 10vo1%. High cross-linking degree and changes in molecular orientation generated γ-APS films with excellent protective performance and ordered arrangement.展开更多
