In this work, Polyaniline/sulfonated MWNT is prepared by an interfacial polymerization method. MWNT was first functionalized with 3,5-phenoxybenzoic acid via ‘‘direct’’ Firedel-Crafts acylation in polyphosphoric acid (PPA)/phosphorous pentoxide (P2O5) medium to afford 3,5-phenoxybenzoyl-functionalized MWNT (H-MWNT). Then, sulfonate to chlorosulforic acid. Aniline was polymerized via an in situ static interfacial polymerization in H2O/CH2Cl2 in the presence of SH-MWNT in organic phase to yield the mixture of PANi-S-MWNT. The product was characterized with a various analytical techniques such as EA, FT-IR, SEM, TEM, TGA, XPS and electrical conductivity measurement. The approach was indeed viable for the hybridization of various carbon nanomaterials and functional polymers to achieve synergistic enhancement stemmed from each component. |
