Adhesive strength and protective capability of composite polymer coatings

Electret composite materials based on polymers: Main properties and new fields of application

“…Since coatings containing electrochemically active fillers (oxides of nonferrous metals) possess electret properties and increased adhesion [12], they have higher sealing ability and rigidity as compared to interlayers without fillers. In addition, these interlayers retard corrosion processes upon contact with metals, thus increasing the serviceability of sealing joints.…”

“…The growth of adhesion depends considerably on the diffusion activated in the electric field for products of contact reactions formed as a result of the electrochemical interaction in the polymer--electrode system. The proposed model of the composite material, including a thermoplastic polymeric binder and dispersed particles of metal oxides, accounts for the increase in adhesion between the components of the material and their electrochemical interaction stipulated by the different value of standard electrochemical potentie!s of metal oxides [12].…”
