But the water solubility of chitosan is poor, which factor has resulted in restriction for its application in many fields. In order to overcome this disadvantage, the chemical modification for chitosan or introducing hydrophilic groups into the amino group and hydroxyl group of chitosan have became important methods. In this paper, the different methods concerned about the hydroxyalkylation of chitosan are discussed. Meanwhile, the applications about the hydroxyalkyl chitosan and their derivatives in medicine, water treatment and tissue engineering materials are presented, and the development trend of hydroxyalkyl chitosan in the future was prospected. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
