Sažetak
The study gives an insight into the research concerning development of electrospun scaffolds as part of the Croatian Science Foundation project. Electrospun composite scaffolds were prepared by electrospinning of neat polycaprolactone (PCL), as well as PCL blended with an antibiotic or silk fibroin separately and finally by electrospinning both PCL/fibroin and PCL/antibiotic within a layered configuration. The scaffolds were analysed in regard to their morphology, total porosity, surface wettability and tensile behaviour taking into account the type of filler and layered structure. The addition of the fillers resulted in the reduction of the water contact angle on the surface of the hydrophobic PCL. Thus, a hydrophilic surface is of paramount importance as it improves scaffolds cells adhesion. Also, the antibiotic and silk fibroin resulted in PCL fibres diameter reduction by 28% and increase by 224%, respectively. Fibers deformations or beads were present in case of the neat PCL and the PCL/fibroin fibres. The biggest pores area was in case of the PCL/fibroin of 8.13±6.45 µm2. The total porosity reduced gradually with the addition of the fillers, resulting in the lowest value in case of the layered scaffolds (from 94.2 to 68.5%). The tensile strength of the electrospun scaffolds improved with the addition of the antibiotic and in case of the layered structure, resulting in the maximum value of 260.33±60.53 cN/mm2. These results suggest that the nature of the filler affects its miscibility with the polymer and electrospinning jet stretching and both porosity and tensile strength are affected by the scaffolds composition and layered structure. In this way by variating the composition and physical structure, scaffolds can be designed according to requirements in tissue therapy and repair.
