摘要：

Modification of polymer properties by incorporation of nanoparticles is a way for the development of advanced membrane materials. New materials based on the compositions polymer fullerene were developed for the use in pervaporation. Two polymers polyphenylene oxide (PPO) and polyphenylene isophtalamide (PA) were modified by fullerene C-60. Their transport properties were studied in pervaporation of two systems: the reacting mixture ethanol acetic acid water ethyl acetate by fullerene-containing PPO membranes and the methanol/cyclohexane mixture with azeotropic point by fullerene-containing PA membranes. The experimental study of sorption-diffusion parameters were carried out in sorption tests to analyze transport properties of the modified membranes as a function of the fullerene content in membranes.
