Summary
This study prepares biocomposite nanofibre scaffolds of polycaprolactone (PCL) reinforced with graphene oxide (GO) by electrospinning, and focuses on how the filler affects their mechanical behaviour. GO nanosheets were dispersed in the PCL fibres, and the morphology and mechanical properties of the resulting mats were characterised in both dry and wet conditions to reflect their intended biomedical use. Incorporating the GO nanosheets successfully improved the mechanical properties of the PCL nanofibres relative to the unfilled polymer. Notably, the best mechanical performance was obtained at low GO loading rather than high, indicating that a small, well-dispersed amount of graphene oxide is more effective than heavier filling for reinforcing electrospun PCL scaffolds.
