Abstract
At present the applications of the conductive polymer are monitor, batteries and the sensors but there have been limitations due to the manufacturing costs, material inconsistencies, toxicity, poor solubility in solvents, and inability to directly melt process. Regarding these problems, in this research to studies the condition to enhance the conductive polymer were conducted via the carbon dioxide plasma technique coated on ITO-PET. The plasma power is 50, 75, 100, 125 and 150 watts in the vacuum conditions for periods 10, 20 and 30 mins respectively. The electrical properties were measured via the 4 point probe. The contact angle for analyzing the hydrophobic was analyzed. The result demonstrated that the power of the plasma and the time has influence on the conductive polymer. With the time for doping at 20 mins the current increased compare to the control item. However, with the time doping at 10 and 30 mins the current decreased. The maximum current at 10 mins doping is 22 mA at the 7 volts in the conduction of 75 watts plasma power. The contact angle of the ITO-PET polymer decrease from 110 degree to 44-95 degree. Henceforth when using the carbon dioxide plasma the phenomenal of hydrophilic increases.
