Grafting of gold nanoparticles and nanorods on plasma-treated polymers by thiols

Popis výsledku v původním jazyce

Grafting of gold nanoparticles and nanorods on the surface of polymers, modified by plasma discharge, is studied with the aim to create structures with potential applications in electronics or tissue engineering. Surfaces of polyethyleneterephthalate andpolytetrafluoroethylene were modified by plasma discharge and subsequently, grafted with 2-mercaptoethanol, 4,4'-biphenyldithiol, and cysteamine. The thiols are expected to be fixed via one of -OH, -SH or -NH2 groups to reactive places on the polymer surface created by the plasma treatment. "Free" -SH groups are allowed to interact (graft) with gold nanoparticles and nanorods. Gold nano-objects were characterized before grafting by transmission electron microscopy and UV-Vis spectroscopy. X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and electrokinetic analysis (zeta potential determination) were used for the characterization of polymer surface at different modification phases. It was proved by
