A novel method for preparing ultra-fine alumina-borate oxide fibres via an electrospinning technique

Abstract

Alumina-borate/PVA composite fibres were prepared using sol–gel processing and an electrospinning technique. After calcination of the thin fibres, ultra-fine fibres of alumina-borate oxide with a diameter of about 550 nm could be prepared. The fibres were characterized by SEM, XRD and FT-IR. The results showed that the crystalline phase and morphology of alumina-borate fibres were largely influenced by the calcination temperature.
