Electrospun PHBV/PEO co-solution blends: Microstructure, thermal and mechanical properties

► Fibrous PHBV/PEO blends (70/30, 80/20, 50/50, in % wt/wt) by electrospinning ► Rougher surface topography of PHBV/PEO blends with respect to the neat PHBV and PEO ► Immiscibility of the two polymeric components by XRD, ATR, TG-DTA, and DSC analyses ► Reduced tensile modulus and comparable elongation at break of PHBV by the PEO blending ► Polymeric fiber rearrangement in the load direction after the tensile tests
