Fabrication and characterisation of chitosan/poly vinyl alcohol nanofibres via electrospinning

In this study, chitosan nanofibres were fabricated using electrospinning process. Initially, chitosan powders were further deacetylated with sodium hydroxide to deprotonate the polymer chains and decrease the molecular weight. Subsequently, the treated chitosan (5 wt-% in 90:10 acetic acid/water rat...
