The effects of TiO2 contents and UV irradiation treatment on the surface properties of PLA films embedded with TiO2
nanoparticle were investigated. Whereas UV irradiation decreased reflectance of the treated PLA films proportionally with increasing
UV energy, the reflectance of PLA/TiO2 films increased with increasing UV energy. The UV irradiation treatment caused PLA/TiO2
blend films more polar as indicated in the generation of new carbonyl group and decrease in zeta potentials, which was more
pronounced with the introduction of TiO2. Upon UV irradiation, TiO2 particles appeared on the film surface as observed in SEM
images. The PLA/TiO2 blend films showed photocatalytic properties such as photobleaching of methylene blue, deodorization of
ammonia and antimicrobial activity in comparison with pure PLA films. |
