Abstract

The sol-gel coating process of stainless steel sheets with SiO₂ films has been studied using CH₃Si(OC₂H₅)₃ as a starting material. The obtained SiO₂ films had improved extensibility over that obtained from Si(OC₂H₅)₄. Results of DTA-TG and infrared spectra showed that CH₃ groups remained in the films even after the heat-treatment at 400°C for 1min. Thus, extensibility of these SiO₂ films was ascribed to the flexible structure resulting from the remaining CH₃ groups.
