Surface hydrophilic modification for hydrophobic electrspun poly(vinyl chloride) nanofibrous membranes by poly(dopamine) coating
The surface hydrophilicity of hydrophobic electrospun poly(vinyl chloride) (PVC) nanofibrous membrane were improved by coating dopamine via the dopamine self-polymerizing and adherring firmly to the membrane surface in mild aqueous environments. The membrane surface hydrophilicity was investigated by water contact angle measurement. The obtained results indicated that the water contact angle of the membrane was reduced significantly compared with the corresponding original membranes. Chemical and morphological changes of the membrane surfaces before and after hydrophilic modification were examined by Fourier transform infrared spectroscopy (FT-IR) and scanning electronmicroscopy (SEM), respectively. It was found that the hydrophilic polymer coating layers containing carboxyl, hydroxyl and amino groups were substantially attached onto the hydrophobic PVC electrospun membrane surfaces.
