Poly-(phenylene-iso-phtalamide) was modified by fullerene C60 and other nanocarbon additives such as nanotubes and soot. These compositions were used for ultrafiltration membranes formation. To estimate the fullerene effect on polyamide properties, intrinsic viscosity and density of compositions containing up to 10 wt% C60 were measured. In addition, overall porosity of asymmetric membranes and contact angle of water on membranes surface were determined. Membranes structure rigidity and resistance to different solvents were estimated by filtration of liquids with different viscosities through membranes modified by 5 wt% fullerene, soot or nanotubes. All nanocomposite membranes were tested in dynamic (ultrafiltration) and static sorption experiments with solution of proteins mixture with different molecular weights to study proteins sorption. Membranes modified by fullerene and nanotubes demonstrated the best values of flux reduced recovery after contact with proteins solution. |
