Abstract: Due to serious environmental pollution and resource shortage,cellulose acetate (CA),as one of the important derivatives of cellulose with excellent processability and biodegradable performance has attracted much attention. In this paper,the applications of CA in textile,cigarette filters and membrane are introduced,and the problems of CA application are analyzed. The research progress of modified CA by different methods,such as blending nano and nano-composite technology and surface modification,are summarized. Development of an industrial modification method and preparation of renewable biodegradable materials should be the focus in the development of cellulose acetate modification.
