Poly(phenylacetylene) (PPA) was prepared with phenylacetylene while multiwalled carbon nanotubes (MWCNTs) were purified and oxidized. The MWCNTs and PPA were then treated in toluene by ultrasonic dispersion. Results showed that the oxidized MWCNTs were coated by PPA and had a stable dispersion in toluene for more than one month. Structural changes of oxidized MWCNTs were analyzed by Fourier transform infrared (FTIR) spectrum, acid-base titration, and Raman spectrum. The dispersion of purified, oxidized, or PPA wrapped MWCNTs was investigated by using high resolution transmission electron microscopy (HRTEM).

Key words: Multiwalled carbon nanotubes, Poly(phenylacetylene), Noncovalent functionalization, Dispersivity
