METHOD OF FORMATION OF MICROPATTERN ON POLYMERIC FILMS SURFACES (VERSIONS)

摘要

FIELD: chemical industry; other industries; methods of formation of the micropatterns on the polymeric film surfaces.;SUBSTANCE: invention is pertaining to the field of production of the polymeric films with the micropattern on their surfaces, which may be used, for example, in the capacity of the reflecting components, the components for the optoelectronic devices and the information display systems. The technical problem of this invention consists in simplification of the method of formation of the micropattern on the polymeric films surfaces. The indicated result is attained due to the fact, that at formation of the micropattern on the polymeric films surfaces by action on the film containing at least on one of its sides the coating made out of the substance more rigid, than the polymer of the film. In the capacity of the film use the biaxially oriented film, and the action includes sequential fixation of the film dimension at least in one arbitrarily selected direction and the annealing of the fixed film in the temperature interval from the temperature of its biaxial orientation up to the polymeric film melting point. The method also provides, that after annealing conduct removal of the coating from the film surface.;EFFECT: invention ensures simplification of the method of formation of the micropattern on the polymeric films surfaces.;2 cl, 3 dwg, 3 ex
