Maximizing Performance of the Membranes Based on Quaternized Polysulfone/Polyvinil Alcohol for Biomedical Applications: Rheological Investigations
The rheological response of blends obtained from
quaternized polysulfone and polyvinyl alcohol in N-methyl-2-
pyrrolidone as against structural peculiarity of polymers from the
blend, composition of polymer mixtures, as well as the types of
interactions were investigated. Results show that the variation of
polyvinyl alcohol composition in the studied system determines
changes of the rheological properties, suggesting that the PVA acts as
a plasticizer. Consequently, rheological behavior of complex system,
described by the nonlinear flow curve, indicates the impact of
polyvinil alcohol content to polysulfone solution, in order to facilitate
the subsequently preparation of bioactive membranes.
