| Abstract | Based on silsesquioxanes (SSO) derived from hydrolytic condensation of (vinyl)trimethoxysilane (VMS) and tetraethoxysilane (TEOS), two hybrid films, f-VMS-SSO (f-VS) and f-VMS-TEOS-SSO (f-VTS) modified with 15 wt-% TEOS, were prepared. The anticorrosion properties (corrosion potential, Ecorr, and corrosion current density, Icorr) of the bare aluminum alloy (AA) and the two films on AA were tested by electrochemical measurements with typical potentiodynamic polarization curves. The Icorr values of three samples are significantly different in the order of f-VTS |
