Abstract: | Three-dimensional (3D) carbon nanotube networks (CNNW) have been successfully constructed by a simple solution route for the
first time. The as-obtained networks consist of the ordered alignment of nanotubes cross-linked with a joint-angle of approximately
90°. Also, the joint points in the networks are very stable and the hollowing joints are conducted with the neighbored carbon
nanotubes. These network characteristics would receive much attention to the applications such as electrical conductivity
and even mass transport. Further work found that the as-obtained CNNW and CNNW/silver composites can both be applied as NH3 gas sensors. The solution-phase technique for the construction of CNNWs made the assembling networks possible without introducing
physical and complicated methodologies, providing an alternative way for the next generation carbon nanotube assembly.
