Abstract:A transparent coating for the bronze culture heritage protection were prepared using GPTS-MTMS hybrid modified by the corrosion inhibitor benzotriazole (BAT) and other assistant agents. The composition of coatings was studied via XPS analysis. The results show that the coating is mainly composed of C, Si, O, N and Cu, their state doesnt change before and after the modification, the element Cu exists in the form of Cu2+ ......
