| Abstract: | The relationships between the molecular structure of chitosan, the material composition of membrane and the application properties of membrane were summarizing. The effects of internal factors,such as the deacetylation degree, cross-linking degree, relative molecular weight and environment conditions, such as pH, plasticizer varieties and dosage, other polysaccharides and the storage age of membrane on the properties of membrane such as penetrability, facility and resist-pull intensity were discussed in brief. The applications of chitosan membrane in food preservation, separation and medical treatment were reviewing. It revealed that there is broad prospect for the research and development of chitosan natural resource. |
