  Abstract

Rotary jet spinning (RJS) method is showing a growing interest as one of the most efficient techniques for micro/ nanofibers production. This paper reports the investigation on the influence of the pullulan/PVA blend solution composition, the solvent volatility and spinneret-collector distance on the fiber셲 diameters produced by RJS technique. To optimize the number of required experiments for a complete evaluation, a central composite rotatable design (CCRD) and response surface methodology (RSM) were applied by means of Design Expert software. The fibrous mats morphology and thermal stability were analyzed as a function of the different parameters investigated. It was found a strong dependence of the fiber diameter on the blend composition and DMSO content, which could be explained mainly by the rheological properties of the polymer solution. The Response Surface Methodology analysis shows that the complex influence of the independent variables on the fiber셲 diameter could be fitted by an empirical model.
