摘　　要：功能材料作为当今社会不可或缺的新型材料,是国家重点支持的高新技术领域的重要组成部分。而功能材料的研发离不开对其性能与晶体结构的研究,不同晶型的材料具有不同的功能特性。该文将最新的科研成果转化为实验教学内容,设计了“多功能高性能聚酰胺1相转变”的综合性创新实验,采用二维广角X射线衍射技术,重点研究了聚酰胺1的相转变与温度的变化规律。通过对测试条件的多角度设计,得到更加全面严谨的实验结果,有助于训练学生的逻辑思维能力和综合实验设计能力,加深学生对功能材料结构与性能关系的认识。As an indispensable new material in today’s society,functional materials are an important part of high-tech field supported by the state.The research and development of functional materials are inseparable from the study of their properties and crystal structure,and different crystalline materials have different functional characteristics.In this study,the latest scientific research achievements are transformed into experimental teaching content,and a comprehensive innovative experiment of“multi-functional and high-performance polyamide 1 phase transformation”is designed.Two-dimensional wide-angle X ray diffraction is used to study the phase transition and temperature variation of polyamide 1.Through the multi-angle design of test conditions,more comprehensive and rigorous experimental results can be obtained,which is helpful to train students’logical thinking ability and comprehensive experimental design ability,and deepen their understanding of the relationship between the structure and performance of functional materials.
