AbstractSingle-walled carbon nanotube (SWCNT) and multi-walled carbon nanotube (MWCNT) were functionalized with 3,4-diaminobenzoic acid via “direct” Friedel-Crafts acylation reaction in PPA/P2O5 to afford ortho-diamino-functionalized SWCNT (DIF-SWCNT) and MWCNT (DIF-MWCNT). The resultant DIF-SWCNT and DIF-MWCNT showed improved solubility and dispersibility. To improve interfacial adhesion between CNT and polymer matrix, the grafting of ABPBI onto the surface of DIF-SWCNT (10 wt%) or DIF-MWCNT (10 wt%) was conducted by simple in-situ polymerization of AB monomer, 3,4-diaminobenzoic acid dihydrochloride, in PPA. The resultant ABPBI-g-MWCNT and ABPBI-g-SWCNT showed improved the mechanical and electrical properties.

HCl doped Polyaniline (PANI)/multi–walled carbon nanotube (MWCNT) nanocomposites were first prepared by in–situ chemical polymerization of aniline monomers in the presence of MWCNTs with less structural defects, and then p–toluene sulfonic acid (TSA) doped PANI/MWCNT nanocomposites were obtained by a sequential doping–dedoping–redoping process. The morphology, microstructure, and thermal and electrochemical properties of the resulting nanocomposites were investigated by scanning electron microscopy, fournier infrared spectroscopy, thermal gravimetric analysis, and cyclic voltammetry, respectively. The effects of TSA as the secondary dopant on the microstructure and electrochemical properties were discussed. The results indicated that a significant improvement in the thermal stability could be achieved, while good electrochemical behavior could be remained.
