在美国麻省大学高分子科学系取得博士学位后的周其凤回到北京大学化学系工作。“中国要发展必需靠中国人自己来发展,对于这一点我还是有责任心的。”周其凤这样说道。 回国之后,周其凤继续液晶高分子的基础研究,并承担了国家自然科学基金委员会和国家教委等部门的研究项目。他最先提出并用实验证实:利用共聚合或提高分子量可以将亚稳态液晶高分子转变为稳态液晶高分子。这一方法已被国外同行多次采用并获成功。特别是他设计合成了一类新型液晶高分子并提出侧链液晶高分子中“mesogen—jacketed liquid crystal polymers”(甲壳型液晶高分子)的概念与分子模型,引起许多国际著名专家的极大关注与重视,为液晶高分子的研究与发展又开辟了一方新的天地。从1983年至今周其凤已发
Zhou Qifeng, a PhD student in the Department of Macromolecular Science at the University of Massachusetts in the United States, returned to work at Peking University’s Department of Chemistry. “I still have a sense of responsibility in this regard for China to develop by its own development,” said Zhou Qifeng. After returning to China, Zhou Qifeng will continue the basic research of liquid crystal polymers and undertake the research projects of the National Natural Science Foundation of China and the State Education Commission. He first proposed and experimentally confirmed: the use of copolymerization or increase the molecular weight metastable liquid crystal polymer can be transformed into steady-state liquid crystal polymer. This method has been repeatedly adopted by foreign counterparts and was successful. In particular, he has designed and synthesized a new type of liquid crystal polymer and proposed the concept and molecular model of “mesogen-jacketed liquid crystal polymers” in side-chain liquid crystal polymers, which attracted a great deal of attention from many internationally renowned experts And attention, for the research and development of liquid crystal polymer has opened up a new world. From 1983 till now, Zhou Feng has been sent
