The present invention proposes an electrospinning composition comprising a catalyst
and a functionalized polymer or copolymer bearing one or more epoxy ring, said mixture
further comprises an anhydride, preferably phthalic anhydride as a crosslinking
agent;
wherein the epoxy:anhydride molar ratio in the electrospinning composition is within the
range between 1:1 and 50:1. The present invention further proposes a method for
preparation of such electrospinning composition, electrospun nano/
submicrostructures
prepared using said method and composite material comprising such electrospun
nano/
submicrostructures
