This study explores, for the first time, application of electrospun biobased poly(butylene 2,5-furanoate) (PBF) and poly(pentamethylene (PPeF) mats in biomedical drug delivery fields, through a careful investigation their structure-property relationship. PBF mats, with glass transition temperature (Tg) 25-30 °C an as-spun crystallinity 18.8%, maintained fibrous structure (fiber diameter ~1.3 µm) mechanical properties (stiffness ~100 MPa, strength ~4.5 strain at break ~200%) under treatment physiological conditions (37 °C, pH 7.5). In contrast, PPeF being amorphous Tg 14 underwent significant densification, geometrical density increasing from 0.68 g/cm³ to 1.07 g/cm³, which depressed specific (i.e., normalized by density) properties. DSC analysis revealed that promoted crystallization (reaching 45.9% crystallinity), while showed limited, but interestingly not negligible, structural reorganization. Both materials good cell adhesion were biocompatible, lactate dehydrogenase release exceeding 20% after 48 h. The potential was evaluated using dexamethasone. exhibited controlled profile, ~10% 4 h ~50% 20 demonstrates versatility these biopolyesters applications highlights impact polymer on material performance.
