Abstract
Methods are provided for functionalizing nanoscale fibers and for making composite structures from these functionalized nanomaterials. The method includes contacting a network of nanoscale fibers with an oxidant to graft at least one epoxide group to at least a portion of the network of nanoscale fibers. A network of functionalized nanoscale fibers or buckypapers may include carbon nanotubes having a mean length of at least 1 mm and having an epoxide group grafted onto the nanotubes.
