Abstract: Chitosan were modified and characterized by adding nano-SiOx .The results showed that a great deal of hydrogen bonds formed among chitosan composite films and large amount of hydroxyl groups occurred on the surface of silicon dioxide noparticles. And also it was found that the keeping effect, optical trasmittance, water permeability, mechanical properties and the likes of the films were improved and increased obviously.

Key words: chitosan, nano-SiOx, glycerel monostearte, modification, multiple films
