Preparation and Properties of Flexible MXene/Chitosan/Oxidized Bacterial Cellulose Aerogel Sensor
Highly sensitive and stable conductive aerogel was prepared by electrostatic interaction and chemical crosslinking of genipine by using oxidized bacterial cellulose,chitosan and MXene as substrate.The microstructure of the aerogel was observed by SEM,and the chemical composition and crystal shape of the aerogel were characterized by FT-IR,XPS and XRD.Finally,the pressure sensitive properties and human sensing applications of the composite aerogel were evaluated.The results show that the aerogel has a low mass,and its density is only 1.202 g/cm3.It can realize the response to external force/self-deformation within 500 ms.In a certain external force range,its resistance value changes in the 8 000～2 000 Ω range.The as-prepared aerogel is responsive to human movement and can distinguish between different motion states.
