Synthesis of TiO2 Nanofiber by Solution Blow Spinning (SBS) Method

Abstract

Synthesis of ceramic nanofibers is commonly carried out through electrospinning method. However, with the emergence of solution blow spinning (SBS) technology, spinning of nanofiber and its composites has resulted in a more straightforward and commercially scalable process. In this study, ceramic nanofibers (i.e., TiO2 nanofibers) were synthesized through SBS followed by calcination. Three critical parameters were investigated (i.e., precursor concentration, calcination temperature and time) to produce ready-to-use composite membranes and pure ceramic nanofibers. Characterizations of ceramic membranes and pure nanofibers include scanning electron microscope (SEM) analysis and energy dispersive x-ray (EDX) for elemental component analysis. Insights on the transformation of composite membranes into pure ceramic nanofibers and the role of calcination are also discussed.
