In this contribution we present a technological procedure for preparation of a new flexible material consisting of single-wall carbon nanotubes (SWNTs) and nanocrystalline diamond (NCD). The fabrication process starts from the preparation of a paper made of SWNTs bundles followed by the CVD-growth of NCD in the interior of the SWNT paper. Keeping balance between the two competing processes during the CVD, i.e. growth of diamond particles versus etching SWNTs, is found as a key factor for the formation of a compact SWNT/NCD composite material. From a technological point of view, both processes are influenced mainly by the CVD conditions (temperature, gas composition, etc.) and/or substrate pretreatment. The essential idea of the diamond integration into the SWNT paper is demonstrated and discussed in more details.
