Abstract: | Silica thin films containing organic polymers, such as poly (vinyl alcohol), poly (vinylpyrrolidone) or poly (vinyl acetate), were prepared on PET substrates by the sol-gel method. Poly (vinyl alcohol) was found to be most effective to suppress the water permeability of PET substrates coated with the organic-inorganic composite films among the three. Under the optimal condition, the water permeability coefficient was about 40% of that of PET substrates. The oxygen permeability coefficient was decreased with an increase in the poly (vinyl alcohol) content in the composites and was about 10% of that of PET substrates when a large amount of poly (vinyl alcohol) was included in the composites. |
