In this work, the effect of oxyfluorination on dyeability of low-density polyethylene (LDPE) film was studied in terms of surface analysis and contact angle measurements. The compositions of a mixtured F2-O2 gas were varied within 80-0, 70-10, 60-20, 40-40, and 10-70 by pressure ratio. Surface characteristics, including the functional groups and wettability of the LDPE film were confirmed by FTIR-ATR, XPS, and contact angle analyses. As a result, the oxyfluorinated LDPE film led to a decrease in water and diiodomethane angles, mainly due to the increase of oxygen functional groups and to the decrease of C-F groups with the oxygen pressure. From the dyeability tests, it was found that the oxyfluorination played an important role in the wettabilty for dispersive and basic dyeing agents. Consequently, the mixtured fluorine treatment on the LDPE film was a suitable method for modifying the hydrocabonaceous polymer surfaces.
