  • Stable electrospinning composition for stable Nano-/submicrostructure production and preparation method thereof
    Patent number: 10422053
    Abstract: The present invention discloses an electrospinning composition comprising a catalyst and a functionalized polymer or copolymer bearing one or more epoxy ring. The mixture further comprises an anhydride, preferably phthalic anhydride as a cross-linking agent. Wherein a molar ratio of epoxy to anhydride in the electrospinning composition is within the range of 1:1 to 50:1. The present invention further discloses a preparation method of the electrospinning composition and an electrospun nano-/submicrostructures prepared using the method and composite material comprising the electrospun nano-/submicrostructures.
