Inhoud:
Quantitative analysis of diffusion of mineral (HCl, H2SO4, HNO3) and organic (HCOOH, CH3COOH, C2H5COOH) electrolytes both in hydrophilic (poly(vinyl alcohol) and moderately hydrophilic (Nylon-6, Nylon-6,6) polymer membranes is made. Structural changes in the polymer matrix accompanying diffusive transport and affecting its rate are studied by X-ray structure analysis at wide and small angles. A diffusion model taking into account morphological changes in polymers with different hydrophilicity degrees is proposed and the interrelation between diffusion and structural characteristics is demonstrated.
