【Abstract】 Chitin/Chitosan is a natural polymer rich in natural resources, which has unique chemical and biological properties. More and more countries and research organizations pay much attention to the development of its products. In this paper, preparation, characterization and chemical modification of chitin/chitosan have been described. The application of its modified products in wastewater treatment, medicine, agriculture, food and cosmetic are also reviewed. The possible application in oilfield has been predicted according to the chemical structure of chitin/chitosan which is similar to cellulose.更多还原
