Received Date: 29 September 2021

作为一种典型的智能材料，形状记忆聚酰亚胺（Shape Memory Polyimide，SMPI）因其优异的高温形状记忆效应和做功能力，在航空航天和智能光电等尖端领域展示了广阔的应用前景。本实验通过设计一种简单、有效的装置实现无水无氧条件，以1，3-双（3-氨基苯氧基）苯与4，4’-氧代双邻苯二甲酸酐为原料合成聚酰胺酸前驱体，采用梯度升温法制得SMPI。通过凝胶色谱、红外光谱、动态热机械分析和热重分析等方法对产物进行表征。所得SMPI呈现优异的形状记忆效应，高温下可推翻超过自身重量11.93倍的金属板，具有良好的做功能力。本实验涵盖了高分子化学合成、产物结构表征、力学性能测试及应用，具有较强的综合性；此外，实验现象稳定、重现性好，适合本科实验教学。通过模拟“天问一号”红旗的展开，激发学生科研兴趣，培养创新思维，提高综合素质；同时让学生领略到中国航天的独特风采，增强民族自豪感。
