The effect of hydrophilic surface modification of low density polyethylene(LDPE) byt the plasma gas($O_2$, $N_2$, and $O_2/N_2$) was investigated from the point of view of the functionalities of the generated LDPE surfaces and the contact angle. By virtue of x-ray photoelectron spectra(XPS) and attenuated total reflectance(FT-IR ATR) analysis, the LDPE surfaces treated with plasma were generated with oxygen functionalities of carbonyl, carboxyl, and the like, nitrogen functionalities by nitrogen plasma and mixing of nitrogen and oxygen plasma treatment were identified with. It was found that nitrogen plasma treatment showed with minimum value at contact angle for rf-power and treatment time, we had obtained optimum condition for hydrophilic surface modification at composite parameter, [(W/FM)t] 520~550GJs/kg.
