我们提出了一种简单而通用的方法，选择性地将富勒烯纳米颗粒沉积在纳米级有序自组装的两亲性聚（环氧乙烷）-嵌段聚甲基丙烯酸酯偶氮苯中间体[PEO-b-PMA (Az)]薄膜上。采用再沉淀法制备了纳米富勒烯，并用原子力显微镜（AFM）对c60嵌段共聚物膜的表面形貌进行了表征。所制备的有序c60纳米颗粒可能为制造电子或光催化器件提供了一条有前途的途径。
We present a simple and versatile approach to selectively deposit fullerene nanoparticles on a nano scale ordered self-assembled thin film of amphiphilic poly (ethylene oxide)-block-polymethacrylate with azobenzene mesogen [PEO-b-PMA (Az)]. Fullerene nanoparticles were fabricated by the reprecipitation method, and the surface morphology of the block copolymer film deposited with C 60 nanoparticles was characterized by atomic force microscopy (AFM). The fabricated ordered C 60 nanoparticles may lead to a promising route for fabricating electronic or photocatalytic devices.
