摘要

针对高分子化学实验教学缺乏对学生科研思维培养的问题，本文将胺固化环氧树脂基形状记忆高分子的网络结构调控与性能设置成综合实验，以环氧树脂和聚醚胺为原料，通过体型缩聚设计合成具有形状记忆效应的环氧树脂基形状记忆高分子。利用凝胶含量、示差扫描量热仪、动态热机械分析仪和创意实验分别研究材料的交联密度、玻璃化转变、储能模量、损耗因子和形状记忆性能。引导学生建立高分子材料“化学→结构→性能→功能”科研思维模式，在这个递进关系中将高分子化学与物理重要理论串联起来，使科研思维和创新意识能够得到一定的训练；通过有趣的“变形→固定→回复”的宏观形状记忆效应，学生能够感知微观的玻璃化转变和熵弹性过程，在有趣的实验现象和感官刺激下培养学生对科研的兴趣和创新意识。

Abstract

Aiming at the lack of cultivating students' scientific research thinking in polymer chemistry experiment teaching

this study set the network structure regulation and properties of amine-cured epoxy resin-based shape memory polymers as a comprehensive experiment. Epoxy resin and polyether amine were used as raw materials to synthesize an epoxy resin-based shape memory polymer with a shape memory effect through body three-dimensional polycondensation. Crosslinking density

glass transition

storage modulus

loss factor and shape memory properties of materials were investigated using gel content

differential scanning calorimetry

dynamic thermomechanical analysis and creative experiments. Guide students to establish a scientific research thinking mode of “chemistry → structure → performance → function” for polymer materials

and connect important theories of polymer chemistry and physics in this progressive relationship

to provide training for scientific research thinking and innovation consciousness. Through the interesting macroscopic shape memory effect of “deformation → fixation → recovery”

students can perceive the microscopic glass transition and entropy elastic process

and their interest and innovative awareness in scientific research are fostered by interesting experimental phenomena and sensory stimulation.
