Electrospinning of wheat bran cellulose/TiO2/ZnO nanofibre and investigating the UV blocking and bactericidal properties

Wheat bran cellulose was extracted and using electrospinning method cellulosic nanofibres with/without nano-TiO2 and nano-ZnO were prepared. The three morphological samples of wheat bran, wheat bran/TiO2 and wheat bran/TiO2/ZnO were studied by field-emission scanning electron microscope; the results show the formation of nanofibres. Besides, the results of elemental mapping analysis of samples demonstrate the good distribution of nanoparticles. To prove the existence of materials on the final nanofibres, Fourier transform infrared and energy-dispersive X-ray were done. The gained result showed the presence of all cellulosic groups and nanomaterials. After studying the UV blocking of samples, the results indicate that wheat bran/TiO2/ZnO has an outstanding prevention against the transmission of UV spectra. In addition, the bactericidal property of samples was investigated with both Gram-positive and Gram-negative bacteria, Bacillus cereus and Escherichia coli, respectively. The test result shows that wheat bran/TiO2/ZnO has 100% antibacterial property against both Gram-positive and Gram-negative bacteria.
