Abstract

The discharge was generated between two rectangular parallel-plate copper electrodes using a sinusoidal voltage of 12.8 kV (rms) of frequency 50 Hz and characterized using electrical and optical measurements. The effects of the discharge on the wicking property and weight loss of Lokta paper were studied respectively by the wicking test and gravimetric method. The estimated value of electron density and electron temperature in the discharge were 8.47×10⁸ cm^-3 and 1.29 eV. The results showed a significant improvement in water absorption ability and considerable weight loss (%) in Lokta paper after the plasma treatment.
