文摘

An atmospheric pressure plasma is studied using optical emission spectroscopy Electron temperature and density of the plasma is estimated to be 0.2–0.4 eV and 1014–1015 cm− 3, respectively. The paper shows interesting relation between the generation rate of atomic oxygen and the water contact angle on the treated surface The results show that helium/nitrogen gas is the most effective gas combination to treat PET film substrate. The plasma treatment significantly increased the adhesion of the acrylate coating onto the PET film substrates. The plasma used here can be scaled up for continuous industrial processes.
