| Abstract: | Poly lactid acid(PLA) fiber scaffolds were fabricated in the electrospinning method. The influence of different solvents and preparation parameters was discussed. The fiber surface acquired by using tetrahgdro faran(THF) solvent was porous and the surface was smooth by using C2H2Cl2 solvent. With the increase in the concentration of PLA solution, the fiber diameter increased dramatically and the shape of beads changed from irregular to flat and sphere. With the increase in applied voltage, fiber diameter decreased. |
