| 摘 要： | The purpose of this study is to investigate the effect of composition poly(D,L-lactide-co-glycolide)/poly(ε- caprolactone)(PLGA/PCL)blending on the morphology,shrinkage and degradation behaviors of the electrospun fibers. With the increase of PLGA content in the composite fibers,the average diameter of the electrospun fibers increased from 1.35μm to 1.95μm.The serious shrinking of the electrospun PLGA meshes could be circumvented by adding 20% PCL in the fibers,resulting from the semi-crystalline nature ...
