For the first time, an ultrasonics sonochemistry method is developed to promote the one‐pot hydrosilylation polyaddition polymerization and crosslinking reaction in the preparation of polysiloxane main‐chain liquid‐crystalline elastomers (MC‐LCEs). Due to the extraordinary effect of acoustic cavitation, the polyaddition polymerization and crosslinking reaction can be successfully carried out in an ordinary laboratory ultrasonic cleaner at room temperature, and generates the LCE matrix network in about 30 min. The prepared MC‐LCEs demonstrate good quality, good properties, and stimuli‐actuation performances. Compared to the traditional thermal processing methods for preparing polysiloxane MC‐LCEs, this method exhibits superior properties rapidly, with high convenience and efficiency, and can be a path for batch fabrication at low cost. The work also demonstrates that the ultrasonics sonochemistry method is effective in generating linear main‐chain liquid crystal polymers through hydrosilylation polyaddition and polysiloxane side‐chain LCE matrix through hydrosilylation crosslinking reaction, thus confirming the high availability of ultrasonics sonochemistry in the processes of hydrosilylation polymerization, crosslinking reactions, or synchronous polymerization and crosslinking reactions.

超声声化学辅助制备聚硅氧烷主链液晶弹性体
首次开发了超声声化学方法，以促进聚硅氧烷主链液晶弹性体（MC-LCEs）制备中的单锅氢化硅烷化加聚聚合和交联反应。由于声空化的非凡效果，加成聚合和交联反应可在室温下在普通实验室超声清洗机中成功进行，并在约30分钟内生成LCE基质网络。制备的MC‐LCE具有良好的质量，良好的性能和激励性能。与传统的制备聚硅氧烷MC-LCE的热处理方法相比，该方法具有快速，优越，高效的特性，并且可以低成本地批量生产。
