▎ 摘　　要

NOVELTY - Preparing three-dimensional porous vertically oriented network structure aerogel comprises (i) providing lignosulfonate/acidified single-walled carbon nanotube dispersion, and performing first hydrothermal treatment to obtain lignosulfonate/single-walled carbon nanotube composite hydrogel, (ii) vacuum filtering to make the lignosulfonate porous graphene oxide mixed solution evenly pass through the lignosulfonate/single-wall carbon nanotube composite hydrogel to obtain lignosulfonate/single-walled carbon nanotube/porous graphene oxide composite hydrogel, and (iii) subjecting the lignosulfonate/single-walled carbon nanotubes/porous graphene oxide composite hydrogel and lignosulfonate solution to second hydrothermal treatment to obtain lignosulfonate/single-walled carbon nanotubes/porous reduced graphene oxide composite hydrogel, and freeze-drying to obtain three-dimensional porous vertically oriented network structure aerogel. USE - The three-dimensional porous vertically oriented network structure aerogel is useful in the preparation of flexible pressure sensors (claimed), and also useful in electronic skin, smart robot, portable health monitoring device and other wear-resistant device. ADVANTAGE - The three-dimensional porous vertically oriented network structure aerogel prepares flexible pressure sensors with good recovery compressive properties and fatigue resistance.
