经过几十年的发展,分子凝胶研究取得了巨大的进步.然而,这些研究大多还停留在开发新的胶凝剂、发现新的凝胶体系和揭示新的胶凝机理.在未来的研究中,如何更好地发挥分子凝胶的优势,推进分子凝胶的现实应用已经成为该领域研究人员的共同期盼.考虑到:(1)有序或部分有序小分子胶凝剂三维网络结构的形成是分子凝胶赖以存在的基础,(2)内相多孔网状结构的存在有助于荧光敏感薄膜材料获得良好传感性能,(3)凝胶乳液的液-液两相特点有可能因凝胶作用的发生而转化为固-固(凝胶-凝胶)或固-液(凝胶-液)两相结构等因素,在过去的10年里,作者实验室将分子凝胶策略引入到新型荧光敏感薄膜材料、凝胶乳液和以凝胶乳液为模板的低密度多孔材料制备中,由此,获得了一系列性能优异的敏感薄膜材料和油水分离材料,拓展了分子凝胶研究.本文结合本课题组工作实际,阐述分子凝胶策略在功能表界面材料制备中的应用,提出分子凝胶拓展研究面临的主要挑战,展望分子凝胶拓展研究的前景和发展趋势.
After decades of development, molecular gel research has made great progress.However, most of these studies still remain in the development of new gelling agents, discovering new gel systems and revealing new gelation mechanisms.In a future study , How to give full play to the advantages of molecular gels and promote the practical application of molecular gels has become the common expectation of researchers in this field.We consider that: (1) three-dimensional networks of ordered or partially ordered small molecule gelling agents The formation of the structure is the basis for the presence of molecular gels. (2) The presence of an internal network of porous meshes contributes to the good sensing performance of the fluorescence sensitive thin film material. (3) The liquid-liquid two-phase characteristics of the gel emulsion It may be due to the occurrence of gel into solid-solid (gel - gel) or solid - liquid (gel - liquid) two-phase structure and other factors, the past 10 years, Glue strategy into the new fluorescence-sensitive film material, gel emulsion and gel emulsion as a template for the preparation of low-density porous materials, thus obtaining a series of excellent performance of sensitive film materials and oil-water separation materials, expanding the molecular condensation Glue research. This article combined with the work of the group Explain the application of molecular gels policies in the preparation of the menu interface material presented major challenges facing molecular gel to expand research and looking forward to the prospect and development trend of molecular gels expand research.
