The oxidative modification of polypropylene surface in electrolytic-cathode atmospheric-pressure discharge

The effect of electrolytic-cathode atmospheric-pressure discharge in air on the surface of polypropylene immersed in a solution and on the hydrogen peroxide formation efficiency was studied. It was found that iron(II) sulfate admixtures lead to a substantial increase in the concentration of oxygen-containing groups on the surface and to a decrease in the concentration of hydrogen peroxide in the solution. A possible interpretations of the results is given.
