摘要
纤维素是一种可再生的生物材料,具有良好的力学性能、柔韧性和透气性。通过对纤维素表面进行物理和化学改性,可实现纤维素表面超疏水化,从而扩大纤维素的应用范围。本文概述了纤维素基超疏水材料的研究成果和现状,重点介绍了浸渍法、喷涂法、接枝聚合法、气相沉积法、水热法等方法在滤纸、棉纤维、微球等纤维素基材上构建纤维素基超疏水材料。
The superhydrophobicity of material surface is depended on the combination of low surface-energy substances and micro/nano rough surface structure. This plays an important role in adsorption, self-cleaning materials, corrosion resistance, and low dragging coatings fields. Cellulose is a renewable biomaterial with good mechanical property, flexibility and permeability. The physical and chemical modification on cellulose can change the surface property to achieve desired superhydrophobicity, which significantly extends the application of cellulose. In this review, the research developments of constructing superhydrophobic cellulose-based materials were summarized. The dipping, spraying, grafting, vapor deposition and hydrothermal method for the modification of cotton, filter paper and microspheres were described in detail.
