Amphiphilic block copolymer as well as preparation method and application thereof

The invention relates to the field of polymer chemistry, in particular to an amphiphilic block copolymer as well as a preparation method and application thereof. The invention provides an amphiphilic triblock copolymer which is of a structure of a hydrophilic block A, a hydrophobic block B and a hydrophilic block A. The amphiphilic triblock copolymer is characterized in that the amphiphilic triblock copolymer comprises a polymer as shown in a formula (4): # imgabs0 #, x is an integer of 1-80, and y is an integer of 1-30. The amphiphilic block copolymer provided by the invention has excellent bionic functionality and good biocompatibility, and can meet the requirements of bionic cell membrane functional application. 本发明涉及高分子化学领域，具体地涉及一种两亲性嵌段共聚物及其制备方法和应用。本发明提供了一种两亲性三嵌段共聚物，所述两亲性三嵌段共聚物为亲水嵌段A-疏水嵌段B-亲水嵌段A结构，其特征在于，所述两亲性三嵌段共聚物包括式(4)所示的聚合物：#imgabs0#其中，x为1～80的整数，y为1～30的整数。本发明提供的两亲性嵌段共聚物具有优异的仿生功能性和良好的生物相容性，能够满足仿生物细胞膜功能性应用的要求。
