主 题：Liquid metal Water-triggered materials Self-heating materials Soft actuator
摘 要：Water-triggered materials are receiving increasing attentions due to their diverse capabilities such as easy operation,soft actuation,low cost,environmental friendliness,and many more other ***,most of such materials generally have a long reaction time and require strict preservation conditions,which limit their adaptability in *** this study,a novel water-triggered material based on Al-NaOH-composited eutectic gallium–indium(eGaIn)alloys was proposed and demonstrated,which is rather fast-responsive and *** water is applied,the material thus fabricated would achieve a temperature rise of 40C in just several seconds along with gas production,indicating its big potential to be used as a thermal and pneumatic ***,the new material’s reusability and degradation ability were also *** that,a double-layer-structure smart bandage was designed,whose bulk was filled with Al-NaOH-composited eGaIn while BiInSn served as outer supporting *** to the experiments,a sheet structure with a thickness of 2 mm would support a weight of 1.8 kg after it was subjected to a cooling process,which is much better than the weight-bearing capability of *** addition,a prototype of a water-triggered sphere robot was also fabricated using Al-NaOH-eGaIn,which realized rolling and bouncing behaviors under specific external *** findings indicate the potential value of the present material in developing future wearable devices,soft actuators,and soft robotics.
