NEEDLELESS ELECTROSPINNING OF SILK FIBROIN/POLYCAPROLACTONE BLEND NANOFIBRES

In this study, composite electrospun fibres consisting of silk fibroin and polycaprolactone was fabricated by needleless electrospinning method. The electrospinning of silk fibroin/polycaprolactone blends with different composition ratios was performed with formic acid as a spinning solvent. The effects of blend ratio of silk fibroin/polycaprolactone in spinning solution is investigated as a function of the properties of spinning solution, the morphology of electrospun fibres and the spinning performance of electrospinning process. Result showed that an increase in the weight ratio of polycaprolactone in spinning solution produces a significant effect on the fibre diameter of the electrospun fibre and the spinning performance of process. With an increase in the amount of polycaprolactone in spinning solution decreasing the fibre diameter and the spinning performance of electrospining process. The silk fibroin/polycaprolactone blend fibres had diameters ranging from 200 to 1100 nm.
