In this paper, nano/microfibrils were applied to enhance the mechanical and hydrophobic properties of the sugarcane bagasse fiber films. The successful preparation of nano/microfibrils was confirmed by scanning electron microscope (SEM), X-ray diffraction (XRD), fiber length analyzer (FLA), and ion chromatography (IC). The transparency, morphology, mechanical and hydrophobic properties of the cellulose films were evaluated. The results show that the nanoparticle was formed by the hemicellulose diffusing on the surface of the cellulose and agglomerating in the film-forming process at 40 °C. The elastic modulus of the cellulose film was as high as 4140.60 MPa, and the water contact angle was increased to 113°. The micro/nanostructures were formed due to hemicellulose adsorption on nano/microfilament surfaces. The hydrophobicity of the films was improved. The directional crystallization of nano/microfibrous molecules was found. Cellulose films with a high elastic modulus and high elasticity were obtained. It provides theoretical support for the preparation of high-performance cellulose film.
在本文中，纳米/微纤丝被用于增强甘蔗渣纤维膜的机械性能和疏水性能。通过扫描电子显微镜（SEM）、X射线衍射（XRD）、纤维长度分析仪（FLA）和离子色谱（IC）证实了纳米/微纤丝的成功制备。对纤维素膜的透明度、形态、机械性能和疏水性能进行了评估。结果表明，纳米颗粒是由半纤维素在纤维素表面扩散并在40℃成膜过程中团聚形成的。纤维素膜的弹性模量高达4140.60MPa，水接触角增加到113°。由于半纤维素吸附在纳米/微丝表面而形成了微/纳米结构。膜的疏水性得到改善。发现了纳米/微纤维分子的定向结晶。获得了具有高弹性模量和高弹性的纤维素膜。它为高性能纤维素膜的制备提供了理论支持。
