Nonporous silica films were formed by a sol-gel process using 3-aminopropyl triethoxysilane(APTEOS), which has been one of the widely applied silane coupling agents. The polypropylene(PP) film as substrate was modified by corona-plasma treatment to provide appropriate adhesion between the coating material and the polymer base film. The effects of the pH, water ratio and film storage time on the gas permeability were then investigated. The coated film exhibited very higher barrier property than PP film, with crack-free. |
