Abstract

Plasma reduction of polyethylene (PE) powders with varying gas pressure has been carried out using both the H2O and pure Ar plasmas. Double probe was used to measure the electron density and the electron temperature. Optical emission spectra was used to identify radical species in the plasma and also used for estimation of the gas temperature. Experimental results show that PE powder was reduced only in H2O plasma and the reduction rate was proportional to the gas temperature. This implies that the dissociated products in H2O plasma play an important role in the processes of PE powder reduction and these processes may enhanced by the gas temperature.
