Permeability of Urea in N-Carboxymethyl Chitosan-Poly (Vynilalcohol) Blend Membranes for HemodialysisDOI: 10.7763/ijcea.2013.v4.301 Keywords: Membranes , n-carboxymethyl chitosan , hemodialysis , permeability. Abstract: A series of membranes are prepared by solvent drying method, which were composed of N-carboxymehtyl chitosan blended with poly(vinyl alcohol) [N-CMC/PVA]. The N-CMC/PVA membranes showed improved strength properties and permeability for low-molecular weight compounds. This novel membranes exhibited good permeability properties for small molecules also indicated a decrease in protein adsorption on the surface of membrane. The structure and the morphology of the resulting membranes were characterized by FTIR. NMR, elementary analysis and scanning electron microscopy (SEM).
