FIELD: chemistry.
SUBSTANCE: method consists in conducting successive stages of melt extrusion of polyvinylidene fluoride, isometric annealing of the extruded film, uniaxial stretching, thermofixing, high-voltage polarising, and forming the layers of the electrico-conducting polymer on the film surface by oxidative in-situ polymerization. First, high-voltage polarisation and then forming a layer of an electro-conducting polymer, for example, such as polyaniline, polypyrrole, polyacetylene, polythiophene are carried out. The polarisation is carried out in the temperature regime, at which the film is first held in an electric field at 90°C, and then cooled without turning off the field to room temperature.
EFFECT: invention allows to increase the total porosity of PVDF films while maintaining a high content of crystalline β-form.
