Electrospinning is a novel technique used to fabricate nanometers to micrometers diameter polymeric and ceramic fibers. The morphology and structure of fibers which would be dominated by electrospinning process parameters and calcinations conditions are important when considering practical applications. This paper involves an investigation of how heating rate influence morphology and structure of CoFe₂O₄ nanofibers. The morphology of CoFe₂O₄ nanofibers changes from a continuous fibrous structure for low heating rate to a winding and packed crystallites nature for high heating rate, increasing heating rate also causes an increase in diameter. FTIR and XRD results demonstrate that PVP/CoFe₂O₄ composite nanofibers for all heating rate form CoFe₂O₄ cubic phase with very high crystallinity after calcinations.
