Polyphosphoric acid (PPA) with optimized P2O5 content as
an electrophilic-substitution-reaction medium is indeed
benign and effective for the covalent attachment of
polyetherketones onto the surface of the electron-
deficient MWNT and VGCNF. Furthermore, on the basis of
all supportive evidences, this work provides one of the
most efficient methods to directly and uniformly grafting
the surfaces of carbon nanotubes (CNT) and nanofibers
(CNF) without or minimum damages. More importantly, the
fact that the isolated nanocomposites were easily
processed and fabricated with the conventional molding
techniques and 5 wt% nanocomposite/PPA dopes could be wet-
spun into a single fiber simply by the force of gravity.
With this value-added feature, their commercialization
potential should be greatly enhanced. This work is
envisioned that one of the best tools in the field of
chemical modification of carbon nanomaterials for
application-specific purpose without concerning
interfacial interaction between carbon nanomaterial and
matrix, which often considered in physical dispersion of
carbon nanomaterial into matrix.
