Biodegradable Poly(butylene succinate), PBS, was photooxidized by UV/ozone irradiation and the effect of
UV energy on the surface properties of the UV-irradiated PBS film were investigated by the measurement of reflectance,
surface roughness, contact angles, chemical composition, and zeta potential. With increasing UV energy, reflectance
decreased in the visible and ultraviolet regions particularly at the wavelength of 380nm. The irradiation produced
nano-scale surface roughness including the maximum peak-to-valley roughness increased from 106nm for the unirradiated
sample to 221nm at the UV energy of 10.6J/cm². The improved hydrophilicity was due to the higher O1s/C1s resulting
from the introduction of polar groups such as C-O and C=O bonds. The surface energy of the PBS increased from
42.1mJ/m² for the unirradiated PBS to 56.8mJ/m² at the irradiation of 21.2J/cm². The zeta potentials of the UV-irradiated
PBS also decreased proportionally with increasing UV energy. The cationic dyeability of the PBS increased accordingly
resulting from the improved affinity of the irradiated PBS surfaces containing photochemically introduced anionic and
dipolar dyeing sites. |
