제목 Preparation of Mullite Nanofibers via Sol-gel and Electrospinning Techniques
초록 Alumina –silica / poly(vinyl alcohol) (PVA) hybrid nanofibers with 300-500 nm diameter were prepared by sol-gel and electrospinning techniques and calcined at high temperatures to obtain ceramic mullite fibers with less than 200 nm diameters. The resulting ceramic fibers were characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), X - ray diffraction (XRD) and FT-IR spectra. TGA showed that the thermal decomposition of hybrid nanofibers was affected by the inorganic content. SEM, XRD and FT-IR results indicated that the morphology, fiber size, and crystalline phase evolution of mullite nanofibers depend upon the calcination temperature.
