英文摘要：

Recent studies on poly（ε-caprolactone）（PCL）blend membrane are summarized.The present paper firstly analyzed the performance of PCL membrane,and pointed out the application limitation of the single component membrane.Then it introduced the blending methods of preparing PCL mixture,mainly including melt blending and solution blending.Next the paper summarized the blend membrane consisted of PCL and synthetic or natural polymers,such as polylactide,polysulfone,chitosan,alginateand so forth,in addition its properties were analyzed,and the potential applications were further summed up in biomedical fields as controllable drug-releasing carriers,medical dressings and tissue engineering scaffolds and so on.The potential values of the blending system were expatiated in biomedical and pharmaceutical materials.
