The effect of formation of a periodic surface microrelief upon tension of polymeric substrates with thin hard coatings under specified conditions (the processing temperature below the glassing temperature, elongation up to 250%, elongation rate <5 mm/min) is described. The microrelief period ranges from 0.5 μm up to hundreds of micrometers, its height up to 1 μm. Methods are proposed to measure low values of the optical path length in media Δn∼λ and azimuthal anchoring energy of a liquid crystal on microreliefed surfaces.
