A study showed a correlation between the dispersion state of MWCNTs in PP and electrical conductivity . The composite was synthesized using two different procedures; 1) chemical modification of MWCNTs and 2) incorporation of a master batch [polypropylene-graftedmaleic anhydride (PP-g-MA)] as a compatibilizer followed by a simple melt blending. Based on the optical microscopic images of MWCNTs/PP composite, the addition of a compatibilizer enhanced the uniform dispersion of MWCNTs in the PP matrix. Although it reduced the conductivity. However, the post-heat treatment improved the interconnection between MWCNTs and PP, leading to higher electrical conductivity. The uniform distribution and construction of a compelling relationship between the composite are crucial. Amphiphilic polymers prevent the aggregation in nanocomposites non-covalently attachment.
