本文通过硫酸水解纸浆,制备了纤维素纳米晶体(CNC).通过环境扫描电镜(SEM)对手性木质纳米纤维素薄膜的形貌进行了表征.利用流变仪测试了纳米纤维素溶液的流变力学性能.利用偏光显微镜(POM)对纳米纤维素薄膜进行了观察.POM观察结果表明CNC薄膜具有手性结构,证明CNC悬浮液在一定条件下能自组装形成胆甾型液晶.SEM观察结果表明,CNC薄膜的形貌特征与溶致胆甾型液晶结构非常相似.

　　Paper pulp was used as the raw material for the preparation of cellulose nanocrytals(CNC)by sulfuric acid hydrolysis.The characterization and the rheologieal mechanie of chiral CNC films were studied by scanning electron microscopy(SEM),Discovery Hybrid Rheometer(DHR)and Polarizing Optical Microscope(POM).The result of POM shows that CNC films have chiral structure and the suspension of CNC can assemble chiral nematic liquid crystals and the result of SEM shows that The characterization of CNC film is s...
