摘要
The combination of carbonaceous foams (CFs) and carbon nanotubes (CNTs) is considered a viable strategy to take advantage of the merits of these two materials. Most of the reported CF-CNT composite embedded the CNTs in the framework of CFs, which may conceal some unique properties of the CNTs. In the present work, CNTs were successfully deposited on the ultra-thin cell walls of a starch-derived CF via a simple flame strategy. Two key factors (the concentration of Ni catalyst and the time of flame treatment) affecting the preparation of the CF-CNT composite were investigated. The CF-CNT composite prepared under optimized conditions has a much larger specific surface area (128.7 m(2) g(-1)) than the CF substrate (1.3 m(2) g(-1)). We demonstrated the potential of the CF-CNT composite for strain sensing. The sensors assembled using the CF-CNT composite as key material were sensitive to compression, bending and stretching.
