Abstract
Biocomposite nanofiber scaffolds of polycaprolactone (PCL) with different graphene oxide surface grafted with poly(ethylene glycol) (GO-g-PEG) concentrations were prepared by electrospinning. Morphological, mechanical as well as wettability characterization were carried out. Results showed that the average diameter of PLA/GO-g-PEG electrospun nanofibers increased by increasing the filler content. GO-g-PEG enhanced the electrospun PCL hydrophilicity as well as the Young modulus, in particular at low GO-g-PEG concentrations.
