本课题建议采用“一锅法”制备具有纳米结构的热固性树脂，其基本思想是让嵌段共聚物在热固性树脂中原位生成, 以此在体系中形成纳米微相并调控体系的纳米结构，最后通过固化得到具有纳米结构的热固性树脂。纳米结构热固性树脂的制备从热固性树脂的前驱体、大分子链转移剂或引发剂及聚合物单体的混合物出发，采用合适的活性聚合方法原位生成嵌段共聚物；取决于原位生成的嵌段共聚物与热固性树脂前驱体的相容性，体系中纳米微相可以反应诱致微相分离也可以聚合诱导的自组装方式形成。本课题重点研究运用这一方法热固性树脂中纳米微相的形成机理、纳米结构的调控以及纳米结构与材料性能的关系。 本研究课题的目标在于推动人们主动运用这一方法实现热固性树脂的高性能化，并运用该方法制备其它具有功能物性材料的新方法。

This project proposes to investigate the preparation of the nanostructured thermosets containing the amphiphilic block copolymers which are in situ rendered via living polymerization in thermosets. The preparation starts from the mixtures of precursors of thermosets, macromolecular chain transfer agent (or macromolecular initiator) and the monomer of the second block of the diblock copolymer; the precursors of thermosets act as the solvents of the living polymerization. The living polymerization was carried out ahead of the curing reaction; the block copolymer was in situ generated in the precursors and then the curing reaction was initiated to afford the nanostructures in thermosets. Depending on the miscibility of the diblock copolymer in situ created, the formation of nanostructures in thermosets would follow either reaction-induced microphase separation or polymerization-induced self-assembly mechanism. The goal of this proposal is to investigate the formation mechanisms of the nanophases, modulation of thermoset morphologies, correlation of morphologies with properties of the thermosets so that ones can actively utilize this novel approach to prepare the nanostructured thermosets. In the meantime, we will also explore to utilize this approach to prepare other nanostructured functional materials.
