Effect of pullulan/poly(vinyl alcohol) blend system on the montmorillonite structure with property characterization of electrospun pullulan/poly(vinyl alcohol)/montmorillonite nanofibers

► PULL/PVA/MMT nanofibers fabrication. ► Good interactions between PULL and PVA caused by possibly hydrogen bonds. ► Different PULL/PVA blend ratios cause different MMT structures. ► Thermal stability of PULL/PVA/MMT nanofibers is influenced by MMT structures.
