Study Effect Coronadischarge on Morphology, Wettability and Antibacterial of Leather

Corona discharge has been used widely to modify polymer and textile materials because it can be operated at an atmospheric pressure in air.This method has been confirmed to be simpler and more practical than any other chemical and physical methods because the samples can be quickly treated under atmosphere pressure and it is environmentally friendly too. In this study, we have studied wettability and antibacterial modify surface leather treatment by corona discharged. An element analysis was done to elucidate the change of chemical composition on the leather surface. The morphology of the modified surfaces also were investigated using scanning electron microscopy (SEM) .The results showed a significant increase in the wettability and antibacterial after treatment leather surface with corona discharge. Micrographs of SEM showed that, with an increase in power and a greater number of passages in the corona treatment, were increased cracks and hoes on the surface samples treated with corona.
