Three polyethylene (PE) types with different branching structures were subjected to air, water and ethanol aerosol‐assisted dielectric barrier discharges (DBD) for surface modification. Using the air DBD the incorporated oxygen concentration was found to be independent on the branching of PE in contrast to the introduction of OH groups, which was PE‐2 > PE‐1 > PE‐3. For water‐aerosol DBD the succession of OH concentration was in the order of PE‐1 > PE‐2 > PE‐3. Ethanol aerosol‐assisted DBD produced the lowest concentration of OH groups also independent on the branching of PE. The chemical nature of introduced oxygen functional groups was inspected by X‐ray photoelectron spectroscopy (XPS) and assigned as CO, >CO/CHO/OCO and OCO.
