MXene Hybridized Polymer with Enhanced Electromagnetic Energy Harvest for Sensitized Microwave Actuation and Self-Powered Motion Sensing
Polymeric microwave actuators combining tissue-like softness with pro-grammable microwave-responsive deformation hold great promise for mobile intelligent devices and bionic soft robots.However,their application is challenged by restricted elec-tromagnetic sensitivity and intricate sensing coupling.In this study,a sensitized polymeric microwave actuator is fabricated by hybridizing a liquid crystal polymer with Ti3C2Tx(MXene).Compared to the initial counterpart,the hybrid polymer exhibits unique space-charge polarization and interfacial polarization,resulting in significant improvements of 230％in the dielectric loss factor and 830％in the apparent efficiency of electromag-netic energy harvest.The sensitized microwave actuation demonstrates as the shortened response time of nearly 10 s,which is merely 13％of that for the initial shape memory polymer.Moreover,the ultra-low content of MXene(up to 0.15 wt％)benefits for maintaining the actuation potential of the hybrid polymer.An innovative self-powered sensing prototype that combines driving and piezoelectric polymers is developed,which generates real-time electric potential feedback(open-circuit potential of～3 mV)during actuation.The polarization-dominant energy conversion mechanism observed in the MXene-polymer hybrid structure furnishes a new approach for developing efficient electromagnetic dissipative structures and shows potential for advancing polymeric electromagnetic intelligent devices.
