The investigation of nanoscale diamond-like carbon (DLC) coatings on acrylonitrile butadiene styrene plastic substrates revealed a linear I–V characteristic, a decrease of both resistivity from 12 Ohm∙m to 3 Ohm∙m, and wetting angle from 52&sup(o) to 38&sup(o) with thickness increased from 54 nm to 71 nm. The relative dielectric permittivity of the DLC coatings varies from 5.6 to 6.5, and at the high frequency limit is completely determined by the real part. It is proposed to consider the conductivity in the system "DLC-coating//adsorbed layer of H&sub(2)O molecules" as a combination of two mechanisms: the hopping conductivity of electrons in the volume of the DLC-coating and the proton conductivity by the Grotthuss mechanism in the adsorbed water molecules layer. It was experimentally established that the variation of air humidity in the range of 16 %–95 % leads to a decrease in the resistance of the system up to 10*3 times. The results demonstrate the potential for developing a humidity sensor based on a DLC-coating and will be also applied in the fabrication of GEM-detectors with resistive coating of the collector electrode.
