초록

The oxygen barrier films were formed on poly(ethylene terephthalate) (PET) substrate by a sol-gel process using 3-aminoproprytrimethoxysilane (APTMOS). The effects of solvent type, coating times and incorporation of fumed silica on oxygen permeability coefficient were investigated. The APTMOS coating film prepared from methanol as a solvent exhibited higher oxygen barrier properties than that using THF. The oxygen permeability coefficient of coated film with APTMOS/methanol by coating 7 times was measured to be $2.28{\times}10^{-6}$, while that of PET film was $1.16{\times}10^{-4}$ GPU. The addition of fumed silica does not affect the oxygen barrier properties. It may be explained that silica particles disrupt chain packing, which leads to an increase in free volume for permeation.
