| 摘 要： | 以纳米纤维素晶须(NCW)为增强体、壳聚糖(CS)为基体,通过流延法制得天然可降解复合膜。通过电子显微镜(SEM)、红外光谱(FT-IR)、X射线衍射(XRD)等手段对复合膜进行结构表征,并对复合膜的动态力学性能、干湿态拉伸性能进行了测试。结果表明:NCW与CS具有很好的相容性;NCW的加入显著提高了CS膜的储能模量、拉伸模量和拉伸强度。NCW能够进一步拓宽CS材料的应用领域和价值。

| Abstract: | Natural biodegradable composite films are prepared from nanocellulose whiskers(NCW) as reinforcement and chitosan(CS) as matrix via solution casting technique.The structures of the films are characterized by SEM,FT-IR,and XRD;Dynamic mechanical properties,tensile performance under dry and wet conditions are also tested.The results show that the composite films exhibite good miscibility;NCW significantly increases films' storage modulus,tensile modulus and strength.NCW promises to further widen applications ... |
