摘要
Recently, multifunctional materials have attracted tremendous attention in intelligent equipment and human–computer interaction, requiring the integration of electrical conductivity, sensing property and heating management. Herein, conductive MXene is formulated and deposited on the PVDF film surface and followed by integrating PI tape to construct a multifunctional PVDF/MXene/PI wearable electronic. The PVDF/MXene/PI with sandwich structure shows ideal mechanical strength and tensile toughness. Based on the conductive MXene network, PVDF/MXene/PI composite possesses excellent mechanosensation ability, which can sensitively monitor different human movements. Besides, PVDF/MXene/PI composite presents prominent Joule heating capability and achieves a temperature of over 80 ℃ at 6.5 V voltage. Insulated high-temperature resistant PVDF and PI tape as protective layers ensure the stability and safety of PVDF/MXene/PI heater. Moreover, PVDF/MXene/PI composite exhibits outstanding electromagnetic interference shielding effectiveness of 40 dB. Finally, PVDF/MXene/PI multifunctional electronic with fascinating multi-functions shows potential applications in human thermotherapy, human–machine interaction and electromagnetic wave protection.
