Abstract: Poly ketone (PK) was photo-oxidized by UV/ozone irradiation and the effect of UV energy on the surface properties of the UV-irradiated PK film was investigated by the measurement of reflectance, surface roughness, contact angles, ESCA, and ATR. Reflectance, particularly at the wavelength of 380nm, decreased with increasing UV energy. And the irradiation produced nano-scale roughness on the surface uniformly. The maximum surface roughness increased from 25.3nm for the unirradiated sample to 104.9nm at the irradiation of 42.4J/cm². The improvement in hydrophilicity was caused by the introduction of polar groups such as C-O and C=O bonds resulting in higher O1s/C1s. The surface energy of PK film increased from 43.3 mJ/m² for the unirradiated sample to 71.9 mJ/m² at the irradiation of 31.8J/cm². The zeta potential of the UV-irradiated PK decreased with increased UV energy and the dyeability to cationic dyes increased accordingly, resulting from the photochemically introduced anionic and dipolar dyeing sites on the PK films surfaces.
