Modification of precursor polymer using co-polymerization: A good way to high performance electrospun carbon nanofiber bundles

Some oxygen-contained olefin derivatives like MBI can effectively improve the pre-oxidation or stabilization process and promote the formation of perfect graphite microstructure in the resulting carbon nanofibers. Those electrospun carbon nanofiber bundles made from the precursor co-PAN polymer with 5 wt% of MBI present an ultrahigh tensile strength of 1.8 GPa and Young׳s modulus of 97.0 GPa.
