在不同溶剂中制备生物质基超疏水材料的研究进展

超疏水材料因具有超高的拒水性以及自清洁能力而备受关注,但是在制备过程中也因所选用溶剂和低表面能物质不同给环境带来不同程度的压力.生物质材料可再生、价格低并且绿色无污染,常用于超疏水材料的制备.本文介绍了生物质基超疏水材料的制备方法,并按照制备技术中所用溶剂不同分类,将生物质基超疏水材料分为有机溶剂型、水基/半水基型、无...

Research Progress in the Preparation of Biomass-Based Superhydrophobic Materials in Different Solvents

Biomass materials are renewable, inexpensive and pollution-free, and are commonly used in the preparation of superhydrophobic materials. Superhydrophobic materials have attracted much attention because of their high water repellency and self-cleaning ability, but they also bring different degrees of pressure to the environment during the preparation process due to the choice of solvents and low surface energy substances. In this paper, the preparation methods of biomass-based superhydrophobic materials are introduced, and according to the different solvents used in the preparation technology, the biomass-based superhydrophobic materials are divided into organic solvent type, water-based/semi-water-based type and non-solvent type, and the advantages and disadvantages of three different types of superhydrophobic materials are summarized. At the end of this article, the measures for preparing environmentally friendly superhydrophobic materials are summarized, and the future development direction of biomass-based superhydrophobic materials is prospected.
