| Abstract [eng] |
Introduction. Plastics have played an important role in the operation of the modern economy, combining remarkable practical properties with affordability. Plastics consumption has dramatically increased by a factor of twenty over the last fifty years and is expected to continue growing in the next 20 years. Therefore, significant attention has been directed towards biobased plastics derived from renewable resources such as plants and biomass. The adoption of biobased polymers in various applications is critical for promoting sustainability and reducing reliance on non-renewable resources. In this research, we investigated the optimisation of parameters for the fabrication of nanofibrous scaffolds made of biobased poly(butylene succinate) [1]. Methods. Biobased poly(butylene succinate) (PBS) pellets (NaturePlast, France) in the two solvent systems (CHCl3/HCOOH) and (CHCl3/CH3OH) were used to fabricate nanofibrous mats by the solution electrospinning technique [2-3]. The experiment plan was designed based on D-optimal interaction model with MODDE® 10 software. The main factors that were investigated during electrospinning were polymer concentration, type of solvent, solvent ratio, and electric field intensity. The fibre morphology was characterised using scanning electron microscopy (SEM) and analysed with ImageJ software. The data collected from the experiment was fitted to partial least square regression model to obtain the response surface plots for the prediction of fibre morphology. Results. A wide range of fibre and pore morphology of electrospun mats was obtained with an average fibre size ranging from 0.17 ± 0.05 μm to 4.54 ± 1.37 μm and a pore size between 1.12 ± 0.50 μm to 13.52 ± 6.57 μm. The polymer concentration and the solvent system appear to be the most significant two factors directly affecting the morphology of electrospun fibrous mats. The fitted model response surface plots (Fig.1) represent the prediction of the fibrous scaffold morphology depending on PBS concentration and the solvent system (ratio, parts) used in the experiment.
