Abstract

Inorganic-organic hybrid films from trimthoxysilylpropylmethacrylate(TMSPM) and tetramethoxysilane (TMOS) or Zr(OC₃H₇)₄ were prepared by the sol-gel method on PET, and their mechanical, optical and water permeation properties were evaluated. The dynamic hardness of the films was higher than that of PET. The hardness of the films increased with an increase in TMOS or Zr(OC₃H₇)₄ content. The water permeability of PET was suppressed by about 10% with the 80TMSPM·20Zr(OC₃H₇)₄ coating.
