Au nanoparticles grafted on plasma treated polymers

Popis výsledku v původním jazyce

Surfaces of 4 thermoplastic polymers (high density polyethylene HDPE, polyethyleneterephthalate PET, polytetrafluoroethylene PTFE, polystyrene PS) were modified by plasma discharge and subsequently grafted with dithiol to introduce thiol (-SH) groups. Biaxially oriented PE in the form of 40 mým thick foils, biaxially oriented PET, PTFE and biaxially oriented PS were used. The samples were modified in direct plasma on Balzers SCD 050 device. Exposure time was 120 s, discharge power 8.3 W and the treatment was accomplished at room temperature. Immediately after the plasma treatment the samples were inserted into methanol solution of biphenyl-4,4-dithiol for 2h. To coat the polymers with the gold nanoparticles the plasma treated samples were immersed for2 h into freshly prepared colloidal solution of Au nanoparticles. After the treatment of the plasma modified polymers with dithiol the concentration of free radicals declines since the free radicals mediate the dithiol binding on polymer
