In this work, cellulose nanofibers were extracted from banana fibers via a steam explosion technique. The chemical composition, morphology and thermal properties of the nanofibers were characterized to investigate their suitability for use in bio-based composite material applications. Chemical characterization of the banana fibers confirmed that the cellulose content was ncreased from 64% to 95% due to the application
of alkali and acid treatments. Assessment of fiber chemical composition before and after chemical treatment showed evidence for the removal of non-cellulosic constituents such as emicelluloses and lignin that occurred during steam explosion, bleaching and acid treatments. Surface morphological studies using SEM and AFM revealed that there was a reduction in fiber diameter during steam explosion followed
by acid treatments. Percentage yield and aspect ratio of the nanofiber obtained by this technique
is found to be very high in comparison with other conventional methods. TGA and DSC results showed
that the developed nanofibers exhibit enhanced thermal properties over the untreated fibers.
