In this paper, regenerated silk fibroin/polybutylene terephthalate blended mats were prepared using electrospinning method with different blending ratios. The influence of regenerated silk fibroin/polybutylene terephthalate ratio on the morphology behaviors, fiber diameter and the surface wettability of the blended mats were studied. The morphology of the electrospun fibers were characterized by SEM. The average fiber diameter and its distribution can be obtained from the SEM pictures using software Image J. The average fiber diameter was 280nm to 486nm and it changed with the blending ratio. The contact angles and penetration times were used to characterize the surface wettability of the nanofiber membranes. It was found that with the increase of regenerated silk fibroin amount, the surface contact angles and penetration times decreased, which meant that the wettability was greatly improved.
