► We treated polyamide 6 films using pure helium (He), He/O and He/CF , respectively. ► We investigated the effect of the different plasma gases treatment on the surface modification of atmospheric pressure plasma. ► The addition of O or CF to He plasma had different effectiveness on the polymer surface modification. To investigate the effect of the different plasma gases treatment on the surface modification of atmospheric pressure plasma, polyamide 6 films were treated using pure helium (He), He/O and He/CF , respectively. Atomic force microscopy (AFM) showed rougher surface, while X-ray photoelectron spectroscopy (XPS) revealed increased oxygen and fluorine contents after the plasma treatments. The plasma treated samples had lower water contact angles and higher T-peel strength than that of the control. The addition of small amount of O or CF to He plasma increases the effectiveness of the plasma treatment in polymer surface modification in terms of surface roughness, surface hydrophilic groups, etching rate, water contact angle and bonding strength.
