摘　　要：高分子物理作为高分子专业的核心课程,着重研究高分子独特的物理性能。在高分子体系中,共轭高分子是一类重要的半导体材料,广泛应用于柔性电子领域,成为整个高分子体系中的关键组成部分。然而,传统高分子物理课程通常较少涵盖有关共轭高分子的相关内容。共轭高分子与传统高分子在性质上存在明显差异,其典型特征是半刚性结构,具备强π-π相互作用,从而赋予其独特的物理性能。本文通过综合高分子物理的基本概念与共轭高分子的研究,阐述了共轭高分子在单链、溶液、玻璃化温度、结晶以及力学性能等方面的研究成果,并将其与传统高分子性能进行了对比。这些研究成果不仅有助于深化对高分子物理概念的理解,同时激发学生对创新研究的兴趣,实现科教融合。Polymer physics,as a core course in polymer science,focuses on the study of the unique physical properties of polymers.Within the polymer system,conjugated polymers stand out as a significant category of semiconductor materials widely applied in the field of flexible electronics,serving as a crucial component throughout the entire polymer system.However,traditional polymer physics courses often lack coverage of relevant content related to conjugated polymers.Conjugated polymers exhibit distinct properties compared to traditional polymers,characterized by a semi-rigid structure and strongπ-πinteractions,endowing them with unique physical capabilities.This paper integrates fundamental concepts of polymer physics with research on conjugated polymers,providing a comprehensive exposition of research findings in areas such as single-chain behavior,solutions,glass transition temperatures,crystallization,and mechanical properties.A detailed comparison with the properties of traditional polymers is presented.These research outcomes not only contribute to a deeper understanding of polymer physics concepts but also stimulate students'interest in innovative research,thereby achieving the integration of science and education.
