摘　　要：材料在微观层面上的性能与其宏观功能间的关联关系,是仿生软材料研究领域的主要关注点以及材料设计的基础。以Belousov-Zhabotinsky反应自振荡水凝胶(BZ胶)为代表,这种由化学信号波驱动和调制,从而将微观构象转变和配位调节为具有宏观运动功能的软材料类型,是近年来仿生材料研究的热点之一。该类材料工作于非平衡态,其运动功能具有内驱动性、仿生性、程控性、自适应性和无缆化等特性。本文综述了BZ胶的微观分子构象、化学能-机械能的转换、流变学性能,以及用BZ胶的宏观活性材料制备的软马达的仿生运动功能设计等内容的主要研究进展,讨论了其中亟待解决的关键问题,并提出了未来可行的解决方案。The correlation between the properties of materials at the micro level and their macro functions was the main focus of the research field of biomimetic soft materials and the basis of material design.Represented by Belousov-Zhabotinsky reaction selfoscillating hydrogels(BZ gels),the type of soft materials driven and modulated by chemical signal waves to modulate the microconformational transformation and coordination into macroscopic kinematic functions was one of the hot spots in biomimetic materials research in recent years.This kind of material worked in a non-equilibrium state,and its motion function had the characteristics of internal drive,biomimicry,program control,adaptability and cable-free.In this review,the main progress on the microscopic molecular conformation,chemical energy-mechanical energy conversion and rheology of BZ gel to the bionic motion function design of soft motor prepared by its macroscopic active materialsthis field in recent years were summarized,the key scientific problems that ned to be solved urgently were discussed,the feasible solutions in the future was put forward.
