Abstract:
Covalent surface modification of multiwall carbon nanotubes leads to enhanced nanotube
dispersion in the polymer. Despite this, the mechanical properties of electrospun fibers made of
polymethylmethacrylate containing surface modified nanotubes generally fall below those of fibers
with pristine nanotubes, sometimes below those of pure polymer fibers. We show that covalent
functionalization produces defects in the graphene structure, leading to mechanical weakening of the
nanotube and, therefore, of the nanocomposite
