pH-sensitive photocatalytic activities ofTiO2/poly(vinyl alcohol)/poly(N,N-dimethylaminopropyl acrylamide) composite nanofibers |
| 초록 |
The composite nanofibers of TiO2/poly(vinyl alcohol) (PVA)/poly(N,N-dimethylaminopropyl acrylamide) (PDMAPAAm) hydrogels were prepared by electrospinning to give a novel treatment of acidic waste water. The anatase TiO2 was used as a photocatalyst due to its high photodegradation efficiency. TiO2 was immobilized in the electrospun fibers for the easy recovery of TiO2 after the waste treatment. TiO2/PVA/PDMAPAAm composite nanofibers were characterized using scanning electron microscope (SEM) and X-ray diffractometer (XRD). The hydrogels consisting of PVA and PDMAPAAm were chosen expecting that the acidic waste water could be absorbed quickly by their excellent swelling behavior in acidic condition due to the repulsion among the protonated amine groups in the polymer chains. High efficiency of photocatalytic decomposition of dye was obtained by the fast swelling of hydrogel in the acidic condition and the uniform dispersion of TiO2 by sonication. |
