摘　　要：经硫酸水解制得的纤维素纳米晶(CNC)悬浮液在达到临界质量分数后可以形成具有手性向列型结构的液晶相。CNC悬浮液干燥后,手性结构可以保留,提高了它作为光学材料和模板的应用潜能,使之成为当前研究热点。综述了CNC手性向列型液晶结构的形成机制和调控方法,重点介绍了CNC手性材料的应用研究,并对手性CNC的研究前景进行了展望。Cellulose nanocrystal(CNC)suspension,prepared by hydrolysis of sulfuric acid,could form a liquid crystal phase with chiral nematic structure above the critical mass concentration.The chiral structure of cellulose nanocrystal suspension could be preserved after dried,which improved its application potential as optical materials and templates and attracted lots of researchers attentions currently.The formation mechanism and tuning methods of CNC with chiral nematic liquid crystal phase was reviewed,and applications of CNC chiral materials was introduced.In addition,the future development of CNC was prospected.
