Abstract

Sustainable and bioderived furanoate polyesters are emerging as promising substitutes for petrochemical-derived polyesters, which are mainly applied in packaging, textile, and biomedical fields. This work presents the successful production, for the first time, of electrospun nanofibrous mats based on two furan-based polyesters, i.e., poly(butylene 2,5-furanoate) (PBF) and poly(pentamethylene 2,5-furanoate) (PPeF), which have very similar chemical structure but remarkably different physical and mechanical properties. The feasibility to produce nanofibrous mats of PBF and PPeF by electrospinning was systematically investigated, by optimizing (i) the solubility of the polymers in different solvent mixtures, (ii) the viscosity and concentration of the spinning dopes, evaluated through rheological measurements of the polymeric solutions, (iii) the spinning rate, and (iv) the applied voltage. A detailed morphological analysis of the resulting non-vowen mats, carried out through fieldemission scanning electron microscopy (FESEM), allowed the screening of the best processing conditions for PBF and PPeF, in order to produce electrospun mats suitable for biomedical applications.
