研究兴趣

李卫华教授团队主要运用高分子理论方法和计算机模拟探索聚合物分相的热力学平衡态和动力学, 最近的重点研究课题是嵌段共聚物分相纳米结构的分子设计,也就是通过设计嵌段共聚物分子结构,实现新颖的非传统相结构, 并且计算这些相结构的性能;最终的研究目标是从分子结构出发,理论预测理想的聚合物分相材料。 对于理论研究,最重要的意义体现在为实验预测新结果,最重要的肯定是得到实验的证实。 非常幸运,我们的理论结果已经得到了多个著名课题组的实验证实,包括美国科学院院士F. Bates教授课题组、C. Bates课题组(F. Bates的儿子)、日本名古屋大学Matsushita教授课题组、韩国浦项科技大学Kim教授课题组等。
