IR spectroscopy and electron microscopy have been employed to study the effect of precipitants on the formation of porous structures in poly(vinyl alcohol)-based and modified polyacrylonitrile-based polymer films prepared by the wet casting method. Conditions for formation of porous structures in the polymer films are established as depending on parameters of solubility and pH of precipitants. The spectral method is tested for studying porosity of polymer materials in near and medium IR regions. [ABSTRACT FROM AUTHOR] |
