Abstract:

An electrospinning method was used to produce Poly(butylene succinate) (PBS) nanofibres. The morphology of the fibres was studied considering fibres of different weight concentrations of PBS/CF solution and spun with different diameters of needle-orifice. The results show that the electrospinning process is very difficult and the products are only by few fibres when the weight concentration equals 8%. When the concentration is increased, the eff-iciency is high and the process becomes easy. The morphology of the fibres is more uniform when are spun with a larger diameter of the needle-orifice. The electrospinability ranges between 8 wt% and 14wt% of PBS/CF weight concentration. The thermal properties and the crystallisation of the PBS polymer pellets and electrospun PBS nanofibers were measured by differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD), respectively. In addition, the hydrolytic degradation behaviour of electrospun PBS nanofibres in 1N NaOH solution was observed by using scanning electron microscopy (SEM).
