Saccharomyces cerevisae microfiltration performance of polycarbonate membranes containing chitosan-based polyelectrolyte complexes
Abstract: Polyelectrolyte complexes (PECs) were prepared using chitosan and sulfonated poly(ethylene terephthalate) by the mixture method. Fourier transform infrared spectroscopy, zeta potential, X-ray diffraction, and thermogravimetric analysis were used to characterize the chemical structure, surface charge, crystallinity, and thermal stability of the PECs. To evaluate how PECs affect the water vapor flux and the microfiltration performance, PECs solutions were spread via casting on polycarbonate microporous membranes. The increase in water vapor flux and in the Saccharomyces cerevisae microfiltration performance indicated that the presence of the PECs acts as fixed charges, changing significantly the transport properties of the polycarbonate matrix.
