A carbon nanotube/carbonaceous foam composite: simple preparation and potential application

Carbon Nanotube/Chitosan-Based Elastic Carbon Aerogel for Pressure Sensing

“…To overcome this issue, several methods have been developed, such as the sol−gel process, 11,12 template, 13 and chemical vapor deposition (CVD). 6 , 714−16 However, most of these materials cannot undergo high compressibility due to their disordered or honeycomb structure. For example, compressible CNT-based carbon aerogel with a disordered network-like structure prepared by the sol-gel process showed significant plastic deformation (∼30%) in the first compression cycle (60% strain).…”

“…Compressible and elastic carbon materials have promising applications in flexible piezoresistive sensors owing to their high conductivity, elasticity, and thermal and chemical stabilities . Up to now, great efforts have been made to assemble carbon blocks such as graphene and graphene oxide (GO), − carbon nanotubes (CNTs), , and their composites ,, into compressible carbon monoliths for pressure sensing. Especially, CNTs are promising nanocarbons for fabricating compressible and elastic three-dimensional (3D) carbon networks because of their excellent conductivity and mechanical strength .…”

“…However, insufficient interaction among CNTs causes their 3D structures to suffer from unit slipping upon compression and thus having a low fatigue resistance. To overcome this issue, several methods have been developed, such as the sol–gel process, , template, and chemical vapor deposition (CVD) , − However, most of these materials cannot undergo high compressibility due to their disordered or honeycomb structure.…”
