【摘要】：蠕虫状链模型可以更好地描述非柔性高分子的空间链构象统计,因此被公认为是更加接近真实高分子的粗粒化高分子链模型.本文从蠕虫状链模型的物理特点出发,简单回顾了该模型在自洽场理论方法中的发展历程,着重从三个研究方向总结了近年来蠕虫状链模型在高分子物理研究中的应用:高分子液晶相结构及其转变的研究;几何表面对高分子体系的影响;蠕虫状嵌段共聚物自组装.最后,针对现有理论的发展现状,对未来基于该模型的场论模拟方法的发展方向提出了展望.
[Abstract]:The wormlike chain model can better describe the spatial chain conformation statistics of non-flexible polymers, so it is recognized as a coarse-grained polymer chain model closer to the real polymer. In this paper, based on the physical characteristics of the wormlike chain model, The development of the model in the self-consistent field theory and method is briefly reviewed. The applications of the worm-chain model in polymer physics in recent years are summarized from three research directions: the study of liquid crystalline phase structure and its transformation of polymer; Effects of geometric surfaces on polymer systems; self-assembly of vermicular block copolymers. Finally, the future development of field theory simulation methods based on this model is prospected.
