Prospective on Preparation of Semiconductor Nanoparticles by Using Amphiphilic Block Copolymers as Template

两亲性嵌段聚合物在选择性溶剂中的自组装行为导致其在纳米材料制备过程中具有非常好的应用前景。文中以两亲性嵌段聚合物的基本结构特点及自组装行为为出发点,概述了用于制备半导体纳米材料的两亲性嵌段聚合物的种类及特点,重点介绍了以两亲性嵌段聚合物为模板制备半导体纳米粒子的基本方法及在各种条件下半导体纳米粒子的不同生长机制,并对两亲性嵌段聚合物在制备功能化纳米材料方面的应用进行了展望。

The self-assembly behavior for amphiphilic block copolymers in selective solvent has resulted in their good application prospective for the preparation of nanomaterials. The types and characteristics for amphiphilic block copolymers which could be used to prepare semiconductor nanocrystals is reviewed. The discussion was based on the fundamental structures and self-assembly properties for amphiphilic block copolymers. We focused on the discussion of preparation methods and different formation mechanisms for semiconductor nanoparticles synthesized by using amphiphilic block copolymers as template at different reaction conditions. At the same time,we also forecast the application of amphiphilic block copolymers for the preparation of functional nano-materials in the future.
