Conductive wood sponge with piezoresistive effect and preparation method and application thereof

The invention discloses a conductive wood sponge with a piezoresistive effect and a preparation method and application thereof, the preparation method comprises the following steps: 1) bleaching natural cork wood, removing lignin, removing hemicellulose, washing, freezing and freeze-drying to obtain a wood sponge with a layered structure; and (2) dipping the wood sponge in a conductive nano material solution; after dipping is completed, taking the wood sponge out, extruding repeatedly and then drying to obtain the conductive wood sponge; wherein a conductive nano material in the conductive nano material solution is selected from at least one of graphene, a carbon nano tube, carbon black and Mxene. The conductive wood sponge solves the problems of high cost, complex processing and poor environmental protection performance of conductive aerogel or conductive sponge in the prior art. 本发明公开了一种具有压阻效应的导电木质海绵及其制备方法和应用，该制备方法包括：1)将天然轻木依次经过漂白、木质素脱除、半纤维素脱除、洗涤、冷冻、冷冻干燥，以得到具有层状结构的木质海绵；2)将所述木质海绵于所述导电纳米材料溶液中进行浸渍；在浸渍完成后，将所述木质
