Abstract Poly(butylene terephthalate)(PBT) surface was modified by UV/ozone irradiation
and the effect of UV energy on the surface properties of the irradiated PBT films
were characterized by the reflectance, surface roughness, contact angles, ESCA, and ATR
analyses of the film surface. The surface reflectance, at the short wavelength of visible
spectrum of particularly 400nm, decreased with increasing UV energy. And the irradiation
roughened the film surface uniformly in the nano scale. The maximum surface roughness
increased from 110nm for the unirradiated sample to 303nm at the UV energy of
10.6J/cm². The surface energy of PBT film increased from 50.5mJ/m² for the unirradiated
PBT to 58.8mJ/m² at the irradiation of 21.2J/cm². The improvement in hydrophilicity was
caused by the introduction of polar groups containing oxygens such as C-O and C=O
bonds resulting in higher O1s/C1s. The increased dyeability of the modified film to cationic
dyes may be resulted from the photochemically introduced anionic and dipolar dyeing
sites on the PBT films surfaces. |
