Synthesis of mullite nanofibers via electrospinning technique using polyvinyl butyral as viscosity supplier

In this research continuous mullite (3Al2O3.2SiO2) nanofibers were synthesised via sol-gel, using electrospinning technique followed by sintering at 1200˚C for 2h. The detail of crystallization development , microstructure evolution and structure of the electrospun nanofibers were investigated by scanning electron microscopy(SEM) and X-ray diffraction(XRD) .Results showed that with appropriate selection of polyvinyl butyral(PVB) content (4wt%) , which played the main role in spinability and micromorphological evolution,the pure mullite nanofibers could be result.
