Abstract
Melt polycondensation of citric acid (CA) and diols can form biodegradable thermoset bioelastomers with good biological properties and designed performances. However, their cross-linked structure reveals a big challenge to fabricate submicrofibers or nanofibers via electrospinning. Herein, melt polycondensation of CA and 1,8-octanediol in the presence of poly(ε-caprolactone) (PCL) was performed to fabricate a prepolymer containing high-molecular-weight poly(1,8-octanediol-
