Liquid metals have garnered increasing attention as an emerging class of functional materials in recent years. In this work, an azo polymer coat with photo-responsive properties is successfully applied onto the surface of liquid metal through reversible addition-fragmentation chain transfer (RAFT) polymerization. The photo-responsiveness of the resulting liquid metal/azo polymer hybrid material is thoroughly investigated. Liquid metal nanodroplets grafted with azo polymers exhibit exceptional ultraviolet and near infrared photo-responsiveness due to photothermal effect of liquid metal and isomerization of azo polymer.

液态金属/偶氮聚合物杂化材料的合成、表征和光响应性

近年来，液态金属作为一类新兴的功能材料受到越来越多的关注。在这项工作中，通过可逆加成断裂链转移（RAFT）聚合，成功地将具有光响应特性的偶氮聚合物涂层涂覆到液态金属表面。对所得液态金属/偶氮聚合物混合材料的光响应性进行了彻底研究。由于液态金属的光热效应和偶氮聚合物的异构化，接枝偶氮聚合物的液态金属纳米滴表现出优异的紫外和近红外光响应性。
