  Abstract

The surface of polytetrafluoroethylene (PTFE)-fiberglass composite film was modified with polydopamine (PDA) in order to improve hydrophilic properties and hence to expand its perspective usage for biomedical and blood-contacting applications. Scanning electron microscopy, atomic force microscopy, energy dispersive spectrometer and fourier transform infrared spectra were employed to analyse the surface morphology and the chemical structures of the modified PTFEfiberglass composite films. Hydrophilic property of PTFE-fiberglass composite films was investigated by using water contact angle measurement. The effect of treatment time on the surface morphology and hydrophilicity of PTFE-fiberglass composite films was investigated. The results showed that a dense layer of PDA was formed on PTFE-fiberglass composite films, the water contact angle decreased gradually with the increase in modification time. Moreover, the fastness of PDA layers deposited on the PTFE-fiberglass composite films was studied by using UV/VIS/NIR spectrometer. It was revealed that the PDA layer was stable in distilled water, 0.1 M hydrochloric acid solution and alcohol, but had a poor resistance to 0.1 M sodium hydroxide solution.
