摘要

采用ATRP法制备了结构明确的两亲性嵌段共聚物聚[甲基丙烯酸(

-甲氨基）乙酯-

-甲基丙烯酸（3-（三甲氧基硅基））丙酯]，其在甲醇/水的混合溶液中自组装形成囊泡结构，并通过甲基丙烯酸[3-（三甲氧基硅基）]

丙酯链段中三甲氧基硅基的水解交联，形成了稳定的共聚物囊泡结构。用光散射、SEM和TEM对囊泡的结构进行了表征。所得共聚物囊泡粒子具有温度和pH双重响应性，通过简单调控温度或pH值来实现囊泡粒子的溶解与沉淀收集，可用于蛋白质等的分离与纯化。

Abstract

A well-defined block copolymer of poly(DMAEMA-b-TMS) was synthesized via ATRP. The obtained poly (DMAEMA-b-TMS) could be self-assembled into vesicles in methanol/water mixture. In addition

the structure of the vesicles was fixed through the crosslinking via polycondensation through the hydrolysis of -Si(OCH

)

groups. The vesicles were characterized by laser light scattering studies and by SEM and TEM analysis. The vesicles are thermo-and pH-sensitive. The solid vesicle particles can easily be redissolved and reprecipitated by manipulating the temperature or pH of the solution and the process is fully reversible.
