In order to expand the application field of electrospinning nanofibers and broaden the material sources of electrospinning process, the recent research progress of electrospinning animal protein nanofibers at home and abroad was reviewed. In view of the denaturation of protein by organic solvents in current electrospinning process,several methods of substituting organic solvents were introduced,and their advantages and disadvantages were compared. It was concluded that water-soluble polymers were more advantageous than organic solvents in the application of protein nanofibers in the field of biomedicine. The influences of cross-linking modification and blending modification on the mechanical properties of electrospun animal protein nanofibers were discussed. The application of electrospun collagen nanofibers in biomedical field was summarized. Finally,the urgent problems and future development directions of electrospun animal protein nanofibers were prospected.
