报告摘要：Entropy, one of the central concepts of thermodynamics, can be a predominant contribution to structural formation and transition in soft matter. However, due to its statistical nature, fundamental explorations of the entropy underlying various, even counterintuitive, phenomena and establishment of the principles of potential entropic contributions to the structures and activities are scarce and still represent challenging tasks. Here we report our effort on exploring the rules and principles regarding entropy effects in soft matter, including clarifying definitely the entropic ordering and entropic force, defining a new concept of superentropic effect, and proposing the strategy to tune the structural organization by controlling entropic effects though external and internal factors of a system. We finally introduce the applications of such an entropic strategy in some representative soft matter systems, such as enhanced dynamical heterogeneity in semiflexible networks, mechanoresponsive hierarchical assembly of nanoparticle in block copolymers, and the rational design of antibacterial macromolecules.
