Different concentrations of PBS/CF solution were prepared by dissolving Poly(butylenes succinate) (PBS) in Chioroform (CF) solvent. Single electrospun nanoporous fiber with an ultra-high specific surface was formed from electrospinning PBS/CF solution in a single processing step. As the concentration of PBS in CF increased, morphology evolved from beads only to ultra-fine continuous fibers. At a suitable concentration, PBS/CF 13%(w/w), uniform nanoporous threads of polymers were emitted from the jet by an electrospinning process. The electrospun nanoporous fibers were fabricated with average porous diameters of similar to 200 nm. The electrospun PBS fibers offer the potential for direct fabrication of biologically based, high-surface-area porous fibers without the use of multiple synthetic steps or post-processing surface treatments.
