Preparation and characterization of polyacrylonitrile/ manganese dioxides- based carbon nanofibers via electrospinning process

This research reports the production of precursor polyacrylonitrile (PAN)/ manganese dioxide (MnO2) nanofibers (NFs) via electrospinning method followed by stabilization and carbonization processes. Nowadays, electrospinning has become a suitable method in manufacturing continuous NFs, thus it is em...
