摘　　要：将材料化学的最新科研成果引入实验教学,设计了碳纳米管/聚氨酯复合弹性体的制备及其热致衰减研究的综合性研究实验。通过FTIR、SEM对碳纳米管(CNTs)的结构和形貌进行了分析,借助适量1.4二氧六环溶剂得到CNTs分散体系,经原位聚合法制备了CNTs/聚氨酯复合弹性体。利用TEM、SEM分析了CNTs对聚氨酯脲弹性体的复合效果,结合“原位”变温红外分析技术和变温力学性能测试技术对聚氨酯弹性体进行了热致衰减分析研究。该实验内容涵盖了原料分析、配方设计、制备方案设计和实施,以及结构表征和性能测试等诸多环节和诸多操作,可增加实验内容的综合性,提高学生的综合素质、科研能力和创新能力。The latest scientific research achievements in material chemistry are introduced into experimental teaching, and a comprehensive research experiment on the preparation and thermal attenuation of carbon nanotube(CNTs)/polyurethane composites is designed. The structure and morphology of CNTs are analyzed by FTIR and SEM. CNTs dispersion system is obtained with an appropriate amount of 1.4 dioxane solvent.CNTs/polyurethane composite elastomer is prepared by in-situ polymerization. The effect of CNTs on polyurethane is analyzed by TEM and SEM. The temperature-dependent FTIR and temperature-dependent mechanical test are combined to study the thermal attenuation of polyurethane. The experiment combines many subjects such as raw material analysis, formulation design and preparation plan design and implementation,structural characterization and performance testing, which can increase the comprehensiveness of the experiment content and improve the students′ comprehensive quality, scientific research ability and innovation ability.
