Cell adhesion behaviors on polyethylene terephthalate surface modified by surface- wave plasma-initiated graft polymerization

摘要

Hydrophilic modification of polyethylene terephthalate (PET) was successfully achieved by surface wave plasma treatment followed by graft polymerization with acrylic acid (AA) monomer. The graft reaction was confirmed by water contact angle measurements and X-ray photoelectron spectroscopy (XPS). 3T3 fibroblast cells were cultured on the AA-modified PET surface. The protein adsorption behaviors were also investigated using an optical waveguide spectroscopy.
