“…Such factors promote matrix-filler interactions rather than filler-filler interactions. The later parameter facilitates geometrical contact between the filler [14]. Next to the thermodynamic factor, the melt-viscosity ratio also decides the localization of the filler in a particular phase in the blends.…”

“…These modifications of the conducting fillers can improve their dispersion in polymer matrices and lead to better response behaviors. Narkis and coworkers employed immiscible polyblends as the matrices of conducting composites for manufacturing solvent sensors, like high impact polystyrene (HIPS)/linear low density polyethylene (LLDPE) [11] and high impact polystyrene (HIPS)/ethylene-vinyl acetate copolymer (EVA) [12]. Their results indicated that the systems are rather sensitive to temperature, swelling and pressure due to the effect of double-percolation as compared with the composites using single polymers as matrices.…”

“…This phenomenon is usually called the ''percolation phenomenon.'' The percolation threshold of PA6-based composites is usually higher than 20 wt% [12][13][14][15] . However, high loading of rigid particles will badly decrease the toughness of the PA6 and, as a result, debasing the value of using this kind of engineering material.…”

Nylon6 (PA6)/Ethylene-(vinyl acetate) (EVA)/carbon black (CB) composites with different electrical conductivity were prepared in an internal mixer. The factors influencing the electrical conductivity of the ternary composites were investigated, including mixing mode, mixing time and mass ratio of PA6 and EVA, and so on. Among three kinds of PA6=EVA=CB composites, including ones prepared by directly mixing (composites A), EVA and CB were mixed prior to melt-compounding with PA6 (composites B) and PA6 and CB were mixed prior to melt-compounding with EVA (composites C), the mixing time only significantly influenced the electrical conductivity of composites A. Good conductivity of the composites could be realized because the distance between CB particles became closer with the increasing of mixing time. However, the mixing time has no effect on the electrical properties of the composites B and the composites C, due to there were no CB particles migrated phenomenon happened. Scanning electron microscopy (SEM) was used to assess the fracture surface morphologies and the dispersion of the CB particles. The results showed that the dispersion of the CB particles significantly affects the electrical conductivity of the composites. Based on the study of the influence of various mass ratios of EVA and PA6 on the morphologies and electrical properties of PA6=EVA composites filled with 10 phr (parts per hundred resins) CB particles, we suggested that the mass ratio of EVA and PA6 affected the volume resistivity of the ternary composites significantly. In addition, the composites were almost insulation when the mass ratios of EVA and PA6 were 80=20 and 70=30, while the composites became conductivity with the mass ratio of EVA and PA6 higher than 60=40. The PA6=EVA=CB composites which CB particles locate at the interface of EVA and PA6 have the lowest volume resistivity when the mass ratio of two components was 60=40.
