Membranas Compuestas: propiedades superficiales y estabilidad térmica

ABSTRACT The composite membranes were manufactured with crosslinking poly(vinyl alcohol) on polyethersulfone porous membranes by coating process. PES membranes were exposed to air plasma for the purpose of surface modification. The coating of the support membrane was carried out by using a polymer matrix with a crosslinking agent. The physico-chemical properties have been studied by attenuated total reflectance fourier transform infrared spectroscopy (ATR-FTIR) and contact angle measurements. Thermal stability properties and phases transition of the composite membranes were investigated by the...
