Abstract:

An allyl poly (ethylene oxide) (PEO) grafted multi-walled carbon nanotubes (MWNT) was synthesized. The packing structure of MWNT-PEO was studied by solid state 13C NMR and TEM. The NMR results showed that the 13C NMR signals of MWNT are observable, and that the PEO chains grafted on the MWNT are amorphous. This demonstrated that there exist n-π interactions between the n orbitals of the PEO ether oxygen and the π system of MWNT.

Key words: solid state NMR, multi-walled carbon nanotubes, poly (ethylene oxide), packing structure
