Polyelectrolyte complex (PEC) membranes of cationic chitosan and anionic sodium alginate with nanofiber structure were synthesized by freeze-drying method.Chitosan and sodium alginate were blended in different concentration and frozen at different temperature.Freeze-drying nanofiber membranes were extensively characterized for their intermolecular interaction, the solution property, thermal stability, morphology and biocompatibility by using FTIR, XRD, Zeta (ζ) potentials, DSC, DTG, SEM and Cytotoxicity assay, respectively.
