熵在纷繁复杂且结构多变的大分子体系中无处不在，不仅深刻影响着其微观结构和宏观物理性能，而且在诸如蛋白质折叠，染色体分离和免疫等生命活动中也扮演着极其重要的角色。探寻大分子体系中的熵效应，对于深入阐释此类体系纷繁复杂现象背后物理机制的重要性来说是不言而喻的，已成为软物质科学与化学、材料以及凝聚态物理等多学科相交叉的重要前沿研究领域。然而，囿于熵的宏观统计性和微观复杂性，其在大分子科学的研究中常常被忽视；与此同时，全面深入的把握熵效应发挥作用的规律仍然存在许多挑战性的难题。例如，熵致有序的物理本质和产生条件是什么？由熵效应产生的力(即熵力)有什么性质，与基本作用力又有何区别？熵效应与焓作用之间是否存在确定的，甚或定量的关联等等。更重要的是，能否在阐释熵效应的基本规律基础之上，进一步地调控熵，并发展出基于熵效应的软物质体系多层级结构调控策略？

       围绕这些基本问题并结合国内外研究现状，清华大学燕立唐教授及其团队开展了系列基础研究工作。本文总结了近年来该团队在大分子和软物质体系熵调控策略方面的系列研究进展。首先，较为深入地剖析了熵致有序的物理内涵，探讨了熵力的独特性和共同特征，并提出和阐释了强熵效应的概念；其次，阐述了熵调控策略的必要性，基本原理以及调控途径；同时，举例介绍了熵调控策略在大分子体系中的应用，涵盖高分子纳米复合体系、凝胶网络、生命大分子体系以及大分子胶体体系等；最后，简明扼要地展望了该领域的未来发展趋势以及面临的关键问题。希冀该论文有助于人们更好地理解大分子及软物质体系一些复杂实验现象背后的熵效应，并为推进基于熵的多层次结构与功能调控策略的发展提供些许启迪。
