This review summarizes the methods to control the morphology and structure of PHBV electrospun nanofibers nanofiber by adjusting the solvent, concentration, additional salts and polymers of PHBV electrospinning solution. Based on the recently research of PHBV nanofibers in tissue engineering and drug delivery carriers, the improvement of hydrophilicity and mechanical properties PHBV nanofibers are emphatically introduced. In addition, some problems existing in preparations and applications of electrospun PHBV nanofibers in biomedical field are further proposed. Finally, the development trends and prospects for PHBV nanofibers are forecasted.
