The preparation of nylon 610/MWNT nanocomposites has been conducted by Friedel-Crafts acylation in an optimized polyphosphoric acid. The resultant functionalized MWNT, which is containing chlorobenzoyl pendants, was homogeneously dispersed tetrachloromethane as organic solvent for interfacial polymerization. The enhanced compatibility of F-MWNT in organic solvents would most probably be originated from the numerous functional groups on the surface of F-MWNT. The state of F-MWNT dispersion in nylon 610/F-MWNT nanocomposite displayed better than that of pristine MWNT (P-MWNT) in nylon 610/P-MWNT. Since our results have demonstrated the simple preparation, scale-up feasibility and processing convenience, the commercialization potential of nylon 610/F-MWNT nanocomposites could be one-step closed.
