Effect of Cellulose and Titanium Dioxide on the properties of Chitosan film

Abstract

Chitosan film has attracted attention due to its advantages; it is easily modified due to numerous active sites. However, the use of chitosan film alone has limited applications. Therefore, it is necessary to modify chitosan film. In this study, chitosan was modified through addition of titanium dioxide and cellulose, extracted from grass (imperata cylindrica). Chitosan-cellulose-titanium dioxide composite film was prepared with different compositions of chitosan, cellulose and titanium dioxide. The result of the tensile test showed the addition of cellulose and titanium oxide improved tensile strength of the chitosan film. FTIR and XRD analysis confirmed the formation of chitosan-cellulose-TiO2 composite film.
