中文摘要： 形状记忆环氧树脂具有形变固定率高、回复力大以及易复合、加工等优点，在航空航天等领域具有广阔的应用前景。然而目前主要研究的双酚A型形状记忆环氧存在性能不佳、原料不可持续性等问题。申请人团队前期研究发现含非平面环材料（包括环氧树脂）表现出优异形状记忆特性，然而对于它的原理和构效关系尚不清楚。因此，本项目拟选择生物来源丰富的含非平面环结构的异山梨醇、糠醇衍生物、松香等为原料设计合成系列不同环结构的生物基环氧树脂，以期得到高性能的形状记忆环氧树脂；同时通过对比研究它们及含平面环对比环氧的形状记忆特性，初步建立含非平面环结构与形状记忆效应之间的构效关系。在此基础上，从非平面环的空间体积作用、弹性、分子运动等多角度去探索研究、归纳总结、初步阐明非平面环结构赋予环氧树脂优异形状记忆效应的原理。为设计合成含非平面环结构或高性能的形状记忆材料提供一定理论基础。

英文摘要： Shape memory epoxy resin has been great potential to be used in many application areas especially in aerospace due to its high fixity, high recovery stress as well as good processability. However, bisphenol A shape memory epoxy resin, as the most investigated shape memory epoxy resin, showed disadvantages such as poor properties as well as unsustainability of bisphenol A. During our previous studies, we found that the non-planar cyclic structure containing polymers including epoxy resin showed excellent shape memory properties. While the mechanism of this phenomenon and the structure-property relationship is unknown. Thus, in this proposal, a series of bio-based epoxy resins with different non-planar cyclic structure will be synthesized to overcome the disadvantages of bisphenol A shape memory epoxy resin, from isosorbide, furfuralcohol derevatives, rosin which are all abundant and renewable resources. And after investigating and comparing the shape memory properties of these bio-based epoxy resins and planar cyclic structure containing epoxy resins for comparison, the relationship between non-planar cyclic structures and shape memory properties will be provided. Furthermore, the mechanism of the excellent shape memory properties of non-planar cyclic structure containing epoxy resin will be studied to provide a scientific basis for the design of high-performance or non-planar cyclic structure containing shape memory polymers.
