                         blend-based multi-wall carbon nanotubes (MWCNT) nanocomposites is 
                         an attractive alternative for the manufacture of electronics 
                         housing as it can have the mechanical and electromagnetic 
                         properties required for this application. The preferred location 
                         of MWCNT in PC/ABS blend is an important parameter to obtain 
                         better mechanical and electromagnetic properties. In this way, 
                         three different blending protocols (BP) were used to obtain 
                         PC/ABS/maleic anhydride-grafted ABS (ABS-g-MAH) (85/10/5) 
                         blend-based MWCNT nanocomposites with the addition of 0.5 and 1 
                         wt% of MWCNT in a twin-screw extruder. Specimens were evaluated by 
                         thermal (thermogravimetric analysisTGA and differential scanning 
                         calorimetryDSC), mechanical (Izod impact strength and tensile 
                         tests), dynamic mechanical analysis (DMA), electrical, and 
                         rheological properties, which were correlated with the 
                         nanocomposites morphology evaluated by high-resolution scanning 
                         electron microscopy. The BP associated with the addition of a 
                         compatibilizer agent influenced the MWCNT distribution and 
                         location in the polymeric matrix. The one-step extrusion process 
                         results in MWCNT mostly at the interface of the PC/ABS blend and 
                         agglomerates, leading to lower mechanical and thermal properties. 
                         The BP in which a PC/MWCNT masterbatch was first prepared and then 
                         diluted in ABS and ABS-g-MAH achieves the higher mechanical 
                         properties, increasing Young's modulus and the ultimate tensile 
                         strength. The third BP in which MWCNT was added in a second step 
                         in the blend already processed resulted in a homogeneous 
                         dispersion of MWCNT on both phases and a lower electrical 
                         resistivity.",
