Abstract:

The optical transmission of oriented porous polyethylene and polypropylene films obtained by the extrusion of a polymer melt with subsequent annealing and uniaxial stretching were studied. The transmission of light by porous films in immersion media such as organic liquids was measured. It is shown that the transmission of light is affected by the closeness of the refractive indices of the polymer and the liquid, as well as by the wettability of the film surface by the liquid. The effect of the degree of orientation and composition of the films on their light transmittance observed when using polar and nonpolar immersion liquids was analyzed.

Keywords:
