主 题：flexible sensor piezoelectric MXene/polyvinylidene fluoride(PVDF)nanocomposite orientation structures
摘 要：With the increasing demand for flexible piezoelectric sensor components,research on polyvinylidene fluoride(PVDF)based piezoelectric polymers is mounting ***,the low dipole polarization and disordered polarization direction presented in PVDF hinder further improvement of piezoelectric ***,we constructed an oriented tertiary structure,consisting of molecular chains,crystalline region,and MXene sheets,in MXene/PVDF nanocomposite via a temperature-pressure dual-field regulation *** highly oriented PVDF molecular chains form approximately 90%of theβ*** addition,the crystalline region structure with long-range orientation achieves out of plane polarization *** parallel orientation arrangement of MXene effectively enhances the piezoelectric performances of the nanocomposite,and the current output of the device increases by nearly 23 *** high output device is used to monitor exercise action,exploring the potential applications in wearable electronics.
