摘　　要：嵌段共聚物在选择性溶剂中能够自组装形成"核-壳"结构的胶束,由于胶束的尺寸处于纳米量级,因此利用嵌段共聚物的自组装制备纳米材料已成为当今高分子科学和材料科学的重要研究课题.刚柔嵌段共聚物是指分子链中同时含有刚性嵌段和柔性嵌段的共聚物,它在溶液中通过不同嵌段对溶剂的选择性可以自组装成球形、棒状、囊泡等多种多样的纳米聚集体.本文简单介绍了嵌段共聚物和分子自组装的概念,总结了刚柔嵌段共聚物在刚棒选择性溶剂、柔性链选择性溶剂和非选择性溶剂中自组装的最新研究进展,并对刚柔嵌段共聚物在溶液中自组装的前景进行了展望.Block copolymers can self-assemble into ＂core-shell＂ micelles in the selective solvent. It has become an important topic in polymer and materials sciences to prepare the functional nano-materials based on the templates of block copolymer self-assembly. Rod-coil block copolymers which consist of rod and coil blocks can be self-assembled into various micellar morphologies including spherical or cylindrical micelles, lamella, vesicles and so on, in the selective solvent for block building block. In this paper, a concept of block copolymer and molecular self-assembly has been simply introduced. It focuses on the development of study on self-assembly of rod-coil block copotymer in rod-selective solvent, coil-selective solvents and non-selective solvent. Moreover, the development tendencies of self-assembly of rod coil block eopolymer in solution have been also discussed here.
