Preparation and Characterization of Conductive blend composites of PP filled with ionic liquids treated-CNT

Abstract According to the facile melt blending method, a series of conductive blend composites based on polypropylene with the excellent electrical conductivityare prepared by Multi-walled carbon nanotube (MWCNT) and ionic liquid (IL). In light of the results of the FTIR and Raman, it was confirmed that the MWCNT was non-covalent modified by IL. The dispersion of MWCNT and the electrical conductivity of the composites are enhanced by the addition of a master-batch as a compatibilizer and IL as a modifier, respectively. With the adding of MWCNTs, the surface resistivity of the conductive blend composites was reduced by 4∼6 orders of magnitude under the same IL loading.
