    Preparation and Properties of Cellulose-Thermoplastic Polyurethane Blend Films

    • 摘要: 利用乙二胺活化纤维素,将活化后的纤维素(Ce)和热塑性聚氨酯(TPU)分别溶于氯化锂(LiCl)-N,N-二甲基乙酰胺(DMAC)体系,制得纤维素-热塑性聚氨酯(Ce-TPU)共混膜。利用傅里叶红外光谱仪(FT-IR)、扫描电子显微镜(SEM)、X射线衍射仪(XRD)、单纤强力仪、折痕恢复性测定仪对共混膜的结构和性能进行表征。结果表明:Ce和TPU相容性良好,w(TPU)=30%时为共混膜的最优配比,此时断裂强力较纯纤维素膜略有提高,断裂伸长率提高了68%,折皱回复角提高了17%,共混膜的抗皱性和弹性有所改善。

       

      Abstract: The cellulose (Ce) was activated by ethylenediamine, and the blend films (Ce-TPU) were prepared by using the activated cellulose as material, solution casting lithium chloride(LiCl)-N,N-dimethylacetamide(DMAC) as solvent system and thermoplastic polyurethane(TPU) as finish agent. Structure and properties of the blend films were investigated by Fourier Infrared spectroscopic analysis (FT-IR), X-Ray Diffraction (XRD), tensile strength test and crease recovery test, respectively. Results demonstrated that the compatibility of cellulose and TPU was good. The optimization ratio of blend films was 30% of TPU mass fraction. For the optimal blend films, the breaking force was slightly enhanced, while the elongation at break was improved by 68%, and the crease recovery angle increased by 17%, the wrinkle resistance and elasticity were better than those of pure cellulose films.
