Abstract This work aimed to overcome chitosan (CS) membrane' drawbacks: mainly stiffness and hydrophobic surface by adding poly(vinyl alcohol) (PVA) and evaluate their biocompatibility. The chemical structure, crystalline and thermal properties were studied by FT-IR, XRD and DSC. The mechanical properties and wettability of CS/PVA membranes were studied by tensile test and static contact angle measurement. In vitro biocompatibility was also evaluated by MTS cytotoxicity assay and SEM examination. The results suggest that adding PVA into CS membrane could greatly improve CS membrane's flexibility and wettability. All the membranes prepared were biocompatible and have potential applications in GTR technology. Copyright © 2012 Elsevier B.V. All rights reserved.
