摘要
从化学及材料前沿领域选取素材,利用现代计算机技术对聚酰亚胺的分子结构进行设计和模拟,比较不同分子构型材料热性能的差异,从分子和原子层面探讨材料单体的分子结构、材料构型以及分子间作用力等对其热性能的影响规律。实验融合了化学、材料、计算机等多学科内容,在培养学生现代材料设计理念,以及对多学科知识的综合运用能力方面取得了良好效果,是“新工科”背景下化学实验改革的一个很好的教学案例。
The experiment was selected from the frontier fields of chemistry and materials.The molecular structure of polyimide(PI)was designed and simulated by using modern computational technology.The differences of thermal properties of the PI materials with different molecular structures were compared,and the effects of molecular structure,material configuration and intermolecular force of the PI monomers on their thermal properties were discussed from the molecular and atomic levels.The experiment integrates multidisciplinary contents including chemistry,material science and computational technology,and has achieved good results in cultivating students’modern material design concept and comprehensive application ability of multidisciplinary knowledge.It is a successful teaching case of chemical experiment reform under the background of“new engineering”.
