摘　　要：嵌段共聚物超分子自组装体形成的有序结构能够提供比共价键更加稳定的连接位点,而有效且快速的退火方法是嵌段共聚物自组装技术中的研究热点。将嵌段共聚物聚苯乙烯-b-聚(4-乙烯基吡啶)(PS-b-P4VP)和3-n十五烷基苯酚(PDP)作为模型体系,三氯甲烷作为溶剂,制备出柱状结构的超分子组装体。功能性链段P4VP与小分子PDP之间具有强氢键作用,在饱和氯仿蒸汽退火的过程中,通过控制退火时间制备出高度有序的柱状结构固体样品。对柱状结构演变过程进行详细探究,扩展了其在多孔碳材料的制备、化妆品纳米载体技术、能量储存/转换装置等方面的应用。Ordered structures formed by block copolymer supramolecular self-assembly can provide more stable bonding sites than covalent bonds.An effective and fast annealing method is still a hot research topic in block copolymer self-assembly technology.The columnar supramolecular assemblage was prepared by using block copolymer polystyrene-b-poly(4-vinylpyridine)(PS-b-P4VP)and 3-n 15alkylphenol(PDP)as model system and trichloromethane as solvent.There is a strong hydrogen bond between functional chain segment P4VP and small molecule PDP.In the process of saturated chloroform steam annealing,highly ordered cylindrical solid samples are prepared by controlling the annealing time.The evolution process of columnar structure is investigated in detail,and its applications in the preparation of porous carbon materials,cosmetics nanocarrier technology,energy storage/conversion device and so on are expanded.
