摘要：

This study aims to prepare a scaffold complex based on O-hydroxyethyl chitosan (O-HECS) for tissue engineering. The characteristics of the scaffold complex were investigated. Chitosan was made to react with ethylene oxide to obtain water-soluble O-HECS. Body-sealing tube polymerization was conducted with stannous octoate as the catalyst and water-soluble O-HECS as the initiator. D,Llactide...
