Cellulose had been molecularly blended to form the true solution through the strong dissolving effect of the solvent N-methyl-morphine-oxide (NMMO) and modified nano-SiO2, modified nano-CaCO3 and Ag composite TiO2 were added into casting film solution. The morphological structure of composite film on the surface was investigated with AFM and SEM. The results showed that the oxygen permeation of cellulose films was improved significantly with the addition of inorganic nano materials. And the performances of nanoparticles composite cellulose film performed best when the additive amount of modified nano-SiO2 was 2%, the additive amount of modified nano-CaCO3 1%, and the additive amounts of Ag composite TiO2 1.5% respectively.
