Abstract

Vacuum filtration method was applied to build optically homogeneous film of palladium (Pd) nanoparticles dispersed multi-walled carbon nanotubes (MWCNTs) networks on plastic substrate. Measurement of the sheet resistance as a function of MWCNTs concentration showed a transition from 2D percolation to 3D conduction behaviour when the concentration of MWCNTs exceeded 0.015 mg/ml. The electrical response to H₂ gas exposure was investigated at room temperature.
