Abstract

Green electrospinning is a flourishing trend in the field of electrospinning (ES) of polymeric/composite materials for biomedical applications. The use of non-toxic solvents instead of the most commonly used solvents in electrospinning is needed to avoid the possible presence toxic solvents traces in the electrospun mats, enhancing their cytocompatibility. It was found that a single solvent or solvent mixtures have a critical role in fiber formation and properties. In this work, fibers in the micro/nanoscale were obtained by electrospinning technique from different poly(epsilon-caprolactone) (PCL) solutions. Benign solvents (i.e. acetic and formic acids, water and their mixtures) and standard organic solvents for ES (i.e. chloroform) were explored in order to compare the fiber characteristics and properties. Morphology, size, crystallinity, thermal and polymer stability of fibers were analyzed. The obtained results showed the suitability of the use of benign solvents for ES, highlighting that for the use of formic acid the degradation of PCL should be taken into consideration.
