摘要：Structural colors,derived from existing natural creatures,have aroused widespread attention in the materials regulation for different ***,inspired by the color adjusting mechanism of hummingbird,we present a novel shape-memory structural color hydrogel film by introducing shape memory polymers(SMPs)into synthetic inverse opal scaffold *** excellent flexibility as well as the inverse opal structure of the hydrogel films imparts them with stable stretchability and brilliant structural *** from the transient structural anisotropy of copolymers,the hybrid films are possessed with shape-morphing behaviors *** on the shape transformations and color responsiveness performance,we have demonstrated diverse structural color actuators with complex shapes for different ***,as the photothermal responsive graphene quantum dots were integrated into the hydrogel,the hybrid films could also be endowed with the feature of light-controlled reversible deformation with synchronous structural color *** features demonstrate that the presented shape-memory structural color hydrogel film is valuable for soft robotics with multifunctions of sensing,communication and disguise.

摘要：小型集水区对气候变化和人类活动极为敏感,而渗漏屏障作为一种自然洪水管理(NFM)策略,以其减缓洪水和生态优势受到重视。文章以Web of Science数据库为基础,对渗漏屏障的作用进行了系统性综述,从洪水控制和生态保护两方面做了深入的归纳与分析。研究表明,渗漏屏障有效地削减洪峰,增加地下水补给,改善水质,并提高河岸带的水土保持能力。此外,渗漏屏障促进了生物多样性和生态系统服务,提供了丰富的微生境,增强了水生生物的栖息和繁殖条件。同时,文章总结了渗漏屏障存在的问题,并提出了对渗漏屏障应用的建议,为环境管理者和工程师提供决策和实施指导。
