液晶性树状高分子

对树状高分子进行功能化,使之成为具有特定性能的新型材料是目前很热门的课题,树状液晶就是其中之一.树状高分子长径比很小,似乎难以形成液晶态,但人们已发现多种树状液晶分子,几乎囊括了所有在其他高分子中出现过的液晶相.本文按液晶相分类,介绍树状液晶高分子的研究进展.

Liquid Crystal Dendritic Polymers

Dendritic polymers including dendrimers and hyperbranched polymers are novel class of synthesized polymers. They have received more and more research interest from materials scientists because of their unique structure characteristics and applications. They are functionalized to given properties, such as liquid crystallinity according to the small length to diameter ratio. Dendrimers display a treelike architecture and are not expected to display liquid crystallinity. But several research groups focused on the self-organization of dendrimers and hyperbranched polymers in liquid crystalline phase and reported many types of liquid crystals, which covered almost all the liquid crystalline phase reported in other polymers. The recent advance in liquid crystal dendritic polymer based on the different types of liquid crystal phases is reviewed in this paper.
