摘要: 针对高等学校高分子科学实验教学项目缺乏时代创新性的现状，提出了将两种聚合策略联用的手段，制备具有光控响应特性的聚合物基软体驱动水凝胶材料，并对其光热驱动行为进行表征，以拓展学生对高分子材料在仿生智能应用领域的认知。本实验首先利用紫外引发聚合的方法制备具有温度响应特性的聚N-异丙基丙烯酰胺(PNIPAM)水凝胶，并进一步联合导电聚合物的原位氧化聚合策略，在PNIPAM水凝胶的内部原位生长具有光热效应的导电聚合物材料，从而制备得到具有光热响应特性的软体驱动复合水凝胶材料，并最终通过近红外光照射的方式，探究所制备光热驱动水凝胶的智能响应驱动性能。本实验立足于当代前沿研究热点，内容既涵盖利用基础聚合方法制备高分子材料，又包含功能性聚合物材料的性能表征，不仅可以夯实学生对高分子聚合方法的理解，还可以拓展学生对功能性高分子材料研究前沿的认知，将有利于提高学生的培养质量。

Abstract: Facing the lack of modernity and innovation in the current polymer science laboratory course during undergraduate education, this experiment proposes a new project for the preparation of photo-thermal responsive soft actuating hydrogel materials based on the combination of UV-initiated polymerization and in situ oxidation polymerization. The proposed experiment will first prepare thermal-responsive poly(N-isopropylacrylamide) (PNIPAM) hydrogel through UV-initiated polymerization. Then the conducting polymer with photo-thermal effect was further introduced into the PNIPAM hydrogel networks based on in situ oxidation polymerization to obtain composite hydrogel with photo-thermal responsive actuating features. Finally, the smart responsive actuating performance of the prepared composite actuating hydrogel was characterized through exposing the hydrogel under NIR irradiation. The proposed experiment focuses on the research hotspot of functional polymer materials, covering both the preparation of polymer materials based on basic polymerization methods and the characterization of functional polymer materials with specific features. The proposed experiment will not only consolidate students’ understanding of polymer polymerization methods, but also expand students’ knowledge of the research frontier of functional polymer materials. The proposed experiment possesses innovation and challenge, which is highly beneficial for improving students’ ability and quality.
