    Fullerene-containing polyphenylene oxide (C60-PPO) asymmetric membranes were prepared by phase inversion technique and compared with PPO asymmetric membranes. To study membrane morphology, atomic force microscopy (AFM) and scanning electron microscopy (SEM) were used. For dynamic characterization, the membranes were tested for permeability and rejection of seven proteins with different molecular weights in an aqueous solution. It was established that fullerene as a component of the C60-PPO mixed matrix polymer system profoundly affects the porous structure formation and the membrane properties.

    Asymetrické polyfenylenoxidové membrány obsahující fulleren byly připraveny technikou inverze fází a porovnány s PPO asymetrickými membránami. Pro studium morfologie byly použity mikroskopie atomárních sil a rastrovací elektronová mikroskopie. Membrány byly dále testovány na propustnost sedmi proteinů o rozličné molekulové váze. Bylo nalezeno, že fulleren silně ovlivňuje porozitu membrán a jejich permeační vlastnosti.
