摘要
近年来超疏水材料的应用领域越来越广泛,对超疏水材料的机械强度、耐磨性、透光度、重复利用性等性能方面的要求越来越高,原料的绿色环保性要求也日渐提高。生物质原料种类多、储量大,占据着可再生资源的主导地位。纤维素作为生物质原料的下游精细产品,具有绿色环保、储量大、应用灵活的优点。本文简单介绍了纤维素基超疏水材料的发展历程、特点及应用,重点分析了水热法、化学沉积法、原子转移自由基聚合和溶胶-凝胶法(纤维素/SiO_(2)超疏水材料和纤维素基气凝胶)等超疏水改性方法在制备纤维素基超疏水材料中的应用。最后对纤维素基超疏水材料的未来发展进行了展望。
In recent years,the application field of superhydrophobic materials has become more and more extensive,and the requirements on mechanical strength,wear resistance,light transmissibility,reuse and other properties of super hydrophobic materials have become higher and higher,and the requirements on green environmental protection of raw materials have been increasing day by day.Biomass materials have many kinds and large volume,which occupy the do minant position of renewable resources.Cellulose,as the downstream fine products of biomass materials,has entered the field of vision of researchers with its advantages of green environmental protection,large reserves and flexible application.This paper briefly indicates the development history,characteristic,and application of superhydrophobic materials and cellulose,the application of superhydrophobic modification methods such as hydrothermal method,chemical deposition method,atom transfer radical polymerization and sol-gel method(cellulose/SiO_(2) super-hydrophobic materials and cellulose aerogel)in the preparation of cellulose based superhydrophobic materials was emphatically analyzed.Finally,the future development of cellulosic superhydrophobic materials was prospected.
