Synthesis and Characterization of Nanofibres of 2ZnO·3B_2O_3·5H_2O Ceramic Composite Using the Sol-Gel Processing and the Electrospinning Techniques

摘要

2ZnO·3B_2O_3·nH_2O (Zinc borate) having the industrially important composite and used as flame retardant, anti-smoke and semiconductor in the electronic circuits was examined different crystal structures. In this study, nanofibers of PVA/zinc nitrate/boric acid composite were prepared by using sol-gel processing and electrospinning technique. By high temperature calcinations of the above precursor fibers, nanofibers of 2ZnO·3B_2O_3·5H_2O composite with diameters of 110 nm could be successfully obtained. The products have been characterized by X-ray powder diffraction (XRD), thermogravimetry (TG) and differential thermal analysis (DTA), scanning electron microscopy (SEM) and FT-IR (Fourier transform-infrared spectroscopy). The effects of experimental conditions on the products were investigated.
