Morphological study of electrospun polybenzoxazine blended with poly(ethylene oxide)

Abstract

In this work, polybenzoxazine (PBZ) based electrospun nanofibers were fabricated with the help of poly (ethylene oxide) (PEO) by electrospinning technique. The influence of PED on the electrospinnability of the BZ solution, the effects of spinning voltage and collecting distance from the tip to the target, on the morphological appearance and average diameter of the as-spun PBZ/PEO blended fibers were investigated. The FE-SEM micrograph showed that for a 6/4 weight ratio of BZ solution to PEO solution, the PEO can enhance the electrospinnability of the BZ solution. The spinning voltage and collecting distance of 4 kV and 25 cm were used, respectively. The diameter of electrospun PBZ/PEO blended fibers was in a range of 600 nm to 1 µm, with a generally uniform thickness along the fiber and high aspect ratio.
