The article presents the results of studies of electrical conductivity and mechanical characteristics of adhesive layers formed by chloroprene rubber-based composites containing various concentrations of carbon nanomaterials (CNM). The presented method of manufacturing adhesive composites based on chloroprene rubber contributes to significant reduction in large aggregates of CNM. It was established that all nano-modified adhesive composites have high adhesion to the surface of the glass plate, except for the composites containing 9 wt.% of electrically conductive fillers. Studies have shown that the most durable adhesive compound was obtained using the adhesive composite, modified with 3 wt.% of CNM Taunit-M, while the adhesive composite containing 6 wt.% of carbon black PrinTex XE2B has the lowest specific volume resistance of 1.43 Ω • cm.
