The effect of aluminum micro- and nanoparticle additions on the dielectric and electrical conducting behavior of low density polyethylene (LDPE) composites were investigated. The micro- and nanocomposites were prepared by meld blending LDPE pellets with aluminum particles in a Brabender mixer, and the mixing time was set for 15 minutes at 200°C to disperse aluminum particles into the polymer matrix uniformly, as well as avoid thermal degradation. Long carbon fibers acted as effective bridges for isolated graphite microparticles, thereby enhancing the continuity of conductive pathways. Results showed that self-passivated Al particles restrict the formation of conductive pathways within polymer matrices of LDPE/Al micro- and nanocomposites.
