The composite material based on multi-walled carbon nanotubes and a water-dispersed paint has been obtained. Low-frequency spectroscopy showed that ultrasonic dispersion of the multi-walled carbon nanotubes (MWCNTs) in the water-dispersion paint leads to a non-monotonic dependences of the complex dielectric constant and electrical conductivity of the composite on the processing time. This behavior is associated with the deagglomeration of MWCNT bundles, the destruction of the MWCNTs at defect sites, and the appearance of extended conductive structures in the bulk composite.
