Development of Polymer Materials with Solar Energy Storage-Exchange Property

本研究旨在开发具有太阳能储存-交换功能的高分子材料。我们成功地大规模合成了3-苯基-2，5-NBD-2-羧酸（PNCA），这类化合物具有优异的光化学活性，可用于太阳能的储存-交换系统。在适宜的反应条件下，通过聚甲基丙烯酸缩水甘油酯的环氧侧基与PNCA的加成反应，大规模制备了含PNCA侧基的聚合物。研究了聚合物的光化学反应性、热储能性能、热稳定性等性能。此外，利用一些新的合成方法合成了各种主链或侧链含有NBD基团的聚合物。也就是说，聚酯与NBD部分在主链和侧链的光敏基团，这具有高的光化学反应性，合成的二缩水甘油醚的2，5-NBD-2，3-二羧酸与二酰氯的加聚反应，然后用光敏化合物使用季鎓盐作为催化剂的所得聚合物的化学改性。通过双环氧化物与2，5-NBD-2，3-二羧酸衍生物的加成反应，合成了主链含NBD结构的聚酯酰胺。通过PNCA等NBD化合物与环氧氯丙烷反应合成含NBD结构的环氧化合物，再与羧酸酐开环共聚，合成了含NBD结构的聚酯。通过含NBD结构的环氧化合物和含光敏基团的环氧化合物与羧酸酐开环共聚，合成了高性能NBD聚酯。然后，评价了这些聚合物在膜态和溶液中的光化学反应性和热能储存性能。

This research project investigated to develop polymeric materials with solar energy storage-exchange property. We succeeded the synthesis of 3-phenyl-2,5-NBD-2-carboxylic acid (PNCA), which have excellent photochemical reactivity for solar energy storage-exchange system, in large scale. Polymers containing pendant PNCA groups were prepared by the addition reaction of pendant epoxide groups in poly (glycidyl methacrylate) s with PNCA under appropriate reaction conditions in large scale. Then, photochemical reactivity, thermal-energy storage property, thermal stability, and other properties of the polymers were investigated. Furthermore, various polymers containing NBD moieties in the main chain or the side chain were synthesized using some novel synthetic methods. That is, polyesters with NBD moieties in the main chain and pendant photosensitizing groups in the side chain, which have high photochemical reactivity, were synthesized by the polyaddition of diglycidyl ether of 2,5-NBD-2,3-dicarboxylic acid with diacyl chlorides followed by the chemical modification of the resulting polymers with photosensitizing compounds using quaternary onium salts as catalysts. Poly(ester-amide) s with NBD moieties in the main chain were synthesized by the polyaddition of bisepoxides with of 2,5-NBD-2,3-dicarboxylic acid derivatives. Polyesters containing pendant NBD moieties were synthesized by the ring-opening copolymerization of epoxy compounds containing NBD moieties, which were synthesized by the reaction of PNCA and other NBD compounds with epichlorohydrin, with carboxylic acid anhydrides. High performance NBD polyesters were also synthesized by the ring-opening copolymerization of the epoxy compounds containing NBD moieties and epoxy compounds containing photosensitizing groups with carboxylic acid anhydrides. Then, photochemical reactivity and thermal energy storage property of these polymers were evaluated in the film state or in solution.
