Application of a high continuous electrical field accelerates the orientation kinetics of polar groups at a polymer–water interface and so improves the surface polarity. This is preliminary to adhesion establishment on a polar substrate. Adhesion of PET and gelatin performed under an electric field leads to an increase of the interfacial adhesion properties, due to simultaneous effects of the electric field at the interface. Polar‐group orientation at a polymer surface and electrical aspects of adhesion are therefore self‐consistent.
