Frequently asked questions

Q1. What have the authors contributed in "Novel three-dimensional carbon nanotube networks as high performance thermal interface materials" ?

To improve the inter-tube in-plane thermal conduction within of VACNT arrays, the authors propose a novel three dimensional CNT ( 3D CNT ) network structure, where the CNTs in a VACNT array are cross-linked by randomly-oriented secondary CNTs. The 3D CNT network grown using this method and is thus chosen for further thermal characterization via a framework especially developed for the evaluation of in-plane thermal properties of such devices. The authors find that the in-plane thermal conductivity of the 3D CNT network is 5. 40±0.
