Preparation and Performances of Amino-SiO₂ Filled Cellulose Film

Abstract:

Coupling agent KH-550 and KH-792 were used for surface modification of fumed silica to get amino group. And then the un- or modified SiO₂ blended with cellulose was added into N-methyl-morphine-oxide (NMMO), a kind of casting solvent, to form the cellulose solution for preparation of films. The modified film was characterized by fourier transform infrared(FTIR), scanning electron microscopy(SEM), mechanical tester and oxygen permeation analyzer. The results showed that the modified SiO₂ can be more evenly dispersed than that unmodified. The un- and modified SiO₂ all can improve the mechanical properties and oxygen permeation of cellulose film when the filled content is about 2wt% and the KH-792 is the best.
