UV irradiation grafting of acrylamide onto dopamine-modified 316L stainless steel
Source abstract
Abstract
UV irradiation grafting technique was applied on a modified 316L stainless steel (SS) surface. The SS sheets were first coated with dopamine by dipping in the dopamine solution with KIO 3 and ultrasonication. Then, the acrylamide (AAm) was grafted onto the dopamine-modified SS samples under UV irradiation with ultrasonication, when the ketone-diol compound was used as a photoinitiating system. For comparison, the UV irradiation grafting of AAm was also performed without ultrasonication. The structures and morphologies of the samples were examined by Fourier transform IR spectroscopy, atomic force microscopy, and scanning electronic microscopy before and after modification, respectively. Results showed that acrylamide was successfully grafted onto the poly-dopamine-coated SS. The hydrophilicity of the modified samples improved significantly, determined by the water contact angle measurement. Shown by Tafel polarization curves, the corrosion potential of modified SS was positively shifted, which demonstrated that the corrosion resistance was improved.
