▎ 摘　　要

NOVELTY - Preparing conductive wood sponge comprises (i) bleaching, removing lignin, removing hemicellulose, washing, freeze-drying of natural balsa wood to obtain a wood sponge with a layered structure; and (ii) impregnating the wood sponge in the conductive nanomaterial solution, taking out wood sponge, repeatedly squeezing, and drying to obtain conductive wood sponge, where the conductive nanomaterial in the conductive nanomaterial solution is graphene, carbon nanotube, carbon black and/or Mxene. USE - The method is useful for preparing conductive wood sponge with piezoresistive effect useful in pressure sensing, human-computer interaction and electronic skin (claimed). ADVANTAGE - The conductive wood sponge solves the problem that the conductive aerogel or conductive sponge in the prior art has high cost, complex processing and bad environmentally-friendly performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for conductive wood sponge with piezoresistive effect.
