| dc.description.abstract | Polyacrylonitrile and its TiO2 composites were electrospun into nanofibers in N, N’-dimethylformamide for photocatalysis and antifouling experiments. The resultants nanofibers were characterized using field emission scanning microscope, Fourier transform infrared spectroscopy, x-ray diffraction, x-ray photoelectron spectroscopy and contact angle analyses. Fourier transform infrared spectroscopy confirmed the formation of polyacrylonitrile-TiO2 composite nanofibers with their diameter ranging from 10 to 340 nm. The x-ray photoelectron spectroscopy results indicate the formation of O–Ti–C bonds on polyacrylonitrile-TiO2 matrix. polyacrylonitrile-TiO2 and polyacrylonitrile nanofiber surfaces showed superhydrophobicity with water contact angle of 155 ± 1 and 154 ± 1, respectively at 120 s. The photocatalytic properties of polyacrylonitrile nanofibers and polyacrylonitrile-TiO2 nanofibers were investigated under a simulated visible light source of 1000 W/m2 using methylene blue. About 90% of methylene blue was degraded within 3 h of exposure using polyacrylonitrile-TiO2 nanofibers while 55% methylene blue degradation was achieved for polyacrylonitrile nanofibers. | en_US |
