Evaluation of the effect of clay in polyethersulfone membranes

Polymeric membranes were produced from nanocomposites of polyethersulfone and clay, in proportions of 3 and 5% by weight of clay, by phase inversion technique using N, N-dimethylformamide as solvent. From X-ray diffraction analysis, an exfoliated and/or partially exfoliated structure was observed. F...
