THE PHENOMENON OF THE STABILITY LOSS OF R IGID COATING DURING TENSILEDRAWING OF POLYMER SUPPORT

The development of a regular microrelief on the surface of the films o f PET and rubbers during their tensile drawing was studied by means of electron microscopy. The surface of the films was coated with a thin platinum layer. The period of the formed microrelief was found to be c ontrolled by the compression of polymer, its mechanical properties, an d thickness of the deposited layer. This phenomenon was considered wit hin the framework of the stability loss of the thin layer, which was i nduced by the compression of rigid coating on the surface of the polym er film. A quantitative analysis of this phenomenon was carried out, a nd a fair correlation between theory and experiment was obtained.
