Abstract: The review of scientific articles devoted to preparation of hybrid structures and widespread methods of impact on structure, composition and organic coating properties was carried out. It was demonstrated that difference between chemical and physical methods to modify and to impact is relative due to similar electrostatic interaction under applied external electric fields as well as between molecules and their fragments, i.e. there are internal electric fields in polyelectrolyte’s solution and at interfaces. The efficiency of complex methods of surface potential modification as well as their prospects were shown by examples.

Keywords: hybrid structures technology, organic structured layers, surface potential, chemical and physical factors, external and internal electrostatic fields, polyelectrolytes.
