以玉米纳米淀粉为基质,甘油为增塑剂、纤维素纳米晶(CNC)为增强剂采用流延成膜法制备玉米纳米淀粉/CNC复合膜,成膜基质和干燥温度对纳米淀粉成膜影响较大,聚氯乙烯基质板对纳米淀粉成膜较好,干燥温度25℃,成膜平整光滑;单因素探讨了玉米纳米淀粉、甘油和CNC含量对纳米淀粉/CNC复合膜强度性能的影响,在该基础上进行三因素三水平正交试验,正交优化研究表明,对玉米纳米淀粉/ CNC复合膜的抗张强度影响为:CNC>甘油>玉米纳米淀粉,正交试验优化结果为CNC 2%,甘油8%,玉米纳米淀粉10%,制备的玉米纳米淀粉/CNC复合膜抗张强度达20.18MPa;FTIR分析表明玉米纳米淀粉、甘油、CNC混合均匀,形成了均一稳定的纳米...

The corn nano-starch/cellulose nanocrystalline(CNC) composite film was prepared by casting method with corn nanostarch as substrate,glycerol as plasticizer and CNC as reinforcing agent. Film forming substrate and drying temperature have influences on film formation of nano-starch,and PVC matrix plate is better. When drying temperature is 25℃,the film forming is smooth and good.The effects of corn nano-starch,glycerol and CNC content on the strength properties of nano-starch/CNC composite film were investigated by single factor,and three factor...
