Nanocrystalline cellulose/Ti3C2TX composite aerogel as well as preparation method and application thereof

The invention relates to a nanocellulose/Ti3C2TX composite aerogel and a preparation method and application thereof, the aerogel is obtained by orderly and densely stacking multiple layers of wavy layered materials, the layered materials are obtained by uniformly mixing nanocellulose and Ti3C2TX, and the surface of each layer of layered material is coated with a layer of methyltrimethoxysilane. The aerogel provided by the invention not only is light in weight, but also has durable high compression elasticity due to the orderly stacked wavy layered structure and hydrophobic property in the aerogel, also has good pressure sensing performance, is used for assembling a pressure sensor with sensitivity as high as 4.05 kPa , response time of 50ms and pressure detection limit of 1Pa, and has wide application prospect. The cellulose-based aerogel can be used for detecting physiological signals such as finger bending, heartbeat and sounding, overcomes the defect that the existing cellulose-based aerogel is diffic
