Surface activation of polyethylene (PE) samples has been carried out using low pressure plasmas (at two different operating frequencies, namely, 40 kHz and 13·56 MHz) dielectric barrier discharge (DBD) (50 Hz frequency at atmospheric pressure), the results are compared. The surface PE exposed to these for various time durations ranging from 1 30 min. treated have also studied their aging behaviour by exposing them ambient atmosphere up 7 days. plasma induced morphological changes were an scanning electron microscope atomic force microscope, while formation functional groups was identified Fourier transform infrared analysis. energy values observed increase 27·5 dyne cm −1 (of untreated PE) 73·8 52·2 after MHz air treatment respectively 35·6 DBD treatment. produced best in PE.
