Selective Grafting of Amine Groups on Polyethylene by Means of NH3-H2 RF Glow Discharges

摘要: Plasma treatments in Radio Frequency Glow Discharges fed with NH3−H2 mixtures have been performed for modifying polyethylene surfaces. Treatment kinetics and the role of species present glow investigated. Actinometric Optical Emission Spectroscopy has utilized as a plasma diagnostic technique. Electron Chemical Analysis studying surface composition treated substrates, which examined both astreated after derivatization amine-functionalities 4-trifluoromethylbenzaldehyde vapors. It found that experimental parameters density active can be controlled to achieve selective grafting of-NH2 among all other nitrogen-containing groups.
