Development of photocatalytic PVA/TiO2 nanofiber membrane by electrospinning and its application for Air Filtration |
| 초록 |
Nanofibers have a large potential in air filtration applications. In this work, we have developed a photocatalytic polyvinyl alcohol (PVA)/TiO2 nanofibers membrane for the treatment of air filtration by using electrospinning method. PVA were electrospun into nanofibrous membranes and TiO2 nanoparticles were loaded in PVA nanofibers in various contents from 10% (w/w) to 50% (w/w). The UV-Vis spectra were conducted for testing the existence of TiO2 nanoparticles in PVA fibers. SEM analysis indicated that TiO2 nanoparticles were loaded on the surface of PVA fibers and dispersed linearly along the fiber direction, which originated from the effect of polarization and orientation caused by high electric field. X-ray diffraction (XRD) was used to determine the crystalline of the membrane. Tensile strength was measured to evaluate the physical properties of the membrane. Therefore, our work suggested that PVA/TiO2 nanofiber membrane has a potential application in air filtration area. |
