“…The chemical functionalisation of carbon nanotubes enables developing completely new composite materials combining the unique properties of nanotubes and other materials, where it becomes possible to control their electrical, mechanical, thermal, and optical properties [10][11][12][13][14][15]. The results of own research and the research pursued by research institutions [16][17][18][19][20][21][22][23] confirm that deposition of nanoparticles of noble metals such as Pd, Pt, Rh, and Au onto a surface of carbon nanotubes may contribute to a substantially higher density of carriers of free loads and hence to nanotubes' enhanced thermal and electrical conductivity. A practical application of the so developed nanotubes-nanoparticles type materials is sensors of selected chemical substances, including H 2 , CH 4 , and NO 2 [24].…”
