PREPARATION OF SILK FIBROIN ELECTROSPUN FIBRES WITH NEEDLE AND ROLLER ELECTROSPINNING TECHNIQUE

Popis výsledku v původním jazyce

In this study regenerated silk fibres were prepared by electrospinning method from silk fibroin in a mixture of formic acid and calcium chloride. An experiment was focused on a comparison of two different spinning techniques between a needle and roller electrospinning. The effects of spinning parameters (e.g., spinning solution concentration, viscosity and surface tension) on morphology of obtained silk fibroin fibres were also studied. It was observed that the concentration of spinning solution playedan important role in spinning ability of silk fibroin solution and the diameter of obtained fibres. An increase of silk fibroin concentration in spinning solution leads to an increase in fibre diameter in both spinning techniques. Average diameter of electrospun fibres produced by roller electrospinning is bigger than electrospun fibres obtained from needle electrospinning. The silk electrospun fibres had diameters ranging from 100 to 1100 nm.
