摘　　要：氮化硼纤维是继炭纤维和炭化硅纤维后广受关注的高性能无机纤维,在航空航天等领域已显示出重要应用前景。聚合物先驱体转化法是其有效的制备方法,合成性能优异的聚硼氮烷先驱体则是该方法的关键。文中介绍了近年来氮化硼纤维聚合物先驱体的最新研究成果,重点综述了先驱体的合成路线及性能,并展望了其未来的研究重点。Boron nitride fibers are of high performance non-oxide ceramic fibers,which cattract people＇s attention after carbon fibers and silicon carbide fibers due to their potential uses in the aviation and spaceflight. Polymer-derived method has become one of the most effective methods to develop boron nitride fibers. Synthesis of precursor with excellent properties is the most important. The latest progress of polymer precursors to boron nitride fibers was reviewed in this paper. Different routes to synthesize polyborazine precursors and their properties were summarized and discussed. At last,the prospect of polymer precursors to Boron nitride fibers is presented in the near future.
