【摘要】：离子液体是指在室温或接近室温情况下呈液态的有机熔融盐。离子液体完全由阴阳离子组成,具有难挥发性、较高的电导率、优良的热稳定性、化学稳定性、宽液程等较好的化学物理性质。其在有机合成、分离、电化学和高分子等领域有着广泛的应用前景,是一种良好的绿色溶剂和电解质。聚离子液体是指由离子液体单体通过聚合生成的,具有阴、阳离子重复单元的一类离子聚合物。聚离子液体兼具高分子聚合物和离子液体的良好性能,能够克服离子液体的流动性,因而在近年来在高分子科学研究领域中有着广泛的背景。此外,基于非共价键相互作用的超分子化学在功能性材料领域中已被广泛研究。在超分子材料领域中,功能超分子凝胶近几年来受到了越来越多的关注。然而(聚)离子液体应用在功能超分子凝胶领域中鲜有报道。针对上述的研究现状,本文主要基于(聚)离子液体超分子凝胶为研究对象,利用超分子相互作用调控(聚)离子液体基超分子凝胶的形成,并更进一步的研究了其性能。本论文研究内容和主要结论如下:(1)基于主客体作用制备超分子离子液体凝胶电解质并应用在准固态太阳能电池中。以β-CD作为主体,双咪唑离子液体(Bis-C12(mim)Br)作为客体,在室温下溶解于1-丙基-3-甲基咪唑(PMII)中,通过主客体包合作用和咪唑离子液体分子间的氢键作用自组装形成凝胶。将该凝胶应用在准固态太阳能电池中,获得了4.61%的光电转换效率和良好的稳定性。(2)基于氢键作用制备咪唑盐聚离子液体的CO_2响应型凝胶。这种咪唑盐聚离子液体(PIL)凝胶是以咪唑类的离子液体、2 (二甲基氨基)甲基丙烯酸乙酯(DMAEMA)为单体,以聚乙二醇二丙烯酸酯(PEG-DA,Mn≈600)为交联剂由自由基聚合而成。通入CO_2气体后,PIL溶液变为透明稳定的凝胶,通入N2后又可以重新恢复到原始的溶液状态。该种CO_2响应材料在智能输送系统和生物材料领域中有着潜在的应用。
[Abstract]:Ionic liquids are organic molten salts that are liquid at or near room temperature. Ionic liquids are completely anion? Cationic composition, high conductivity, high volatility, excellent thermal stability, chemical stability, wide liquid path and other better chemical and physical properties. It has been widely used in organic synthesis, separation, electrochemistry and macromolecule. It is a good green solvent and electrolyte. Polyionic liquids are a class of ionic polymers formed by polymerization of ionic liquid monomers with anion and cationic repeating units. Polyionic liquids (Pils) have a wide background in the field of polymer science because they have good properties of both polymer and ionic liquids, which can overcome the fluidity of ionic liquids. In addition, supramolecular chemistry based on noncovalent bond interaction has been widely studied in the field of functional materials. In the field of supramolecular materials, functional supramolecular gels have attracted more and more attention in recent years. However, the application of ionic liquids in functional supramolecular gels is rarely reported. In view of the above research status, this paper mainly based on the (poly) ionic liquid supramolecular gel as the research object, using supramolecular interaction to regulate the formation of (poly) ionic liquid based supramolecular gel, and further studied its properties. The research contents and main conclusions are as follows: (1) Supramolecular ionic liquid gel electrolyte was prepared based on host and guest interaction and applied in quasi-solid solar cells. 尾 -CD was used as host, diimidazole ionic liquid (Bis-C12 (mim) Br) was used as guest, dissolved in 1-propyl-3-methyl imidazole (PMII) at room temperature, and self-assembled gel was formed by interaction of host and guest with hydrogen bond between imidazole ionic liquid molecules. When the gel was used in quasi-solid solar cells, the photoconversion efficiency and stability were 4.61%. (2) the CO_2 responsive gel of imidazolium polyionic liquids was prepared by hydrogen bonding. The imidazolium salt polyionic liquid (PIL) gel was prepared by free radical polymerization of imidazole ionic liquid (dimethylamino) ethyl methacrylate (DMAEMA) with polyethylene glycol diacrylate (PEG-DA,Mn 鈮，
