Properties of Vanillin Modified Poly(vinyl Alcohol)/Gelatin Composite

Abstract:

To improve the cytocompatibility of super-hydrophilic poly (vinyl alcohol) (PVA) hydrogel, PVA/gelatin (PVA/Gel) composite was modified by vanillin (PVA/Gel/V) in this study. The properties of the composite gels were characterized by SEM, FTIR, DSC and contact angle instrument. The results show that PVA/Gel/V composite can compose a homogeneous system with the addition of vanillin, accompanying some destroy of the intra-hydrogen bonding of PVA crystal molecular chains and decrease of PVA super hydrophilicity. PVA/Gel/V composite exhibits better miscibility and hydrophobicity than pure PVA and PVA/Gel. The modified PVA/Gel/V composite may have a promising prospect for future cartilage repair.
