چکیده انگلیسی
In this study, ethylene propylene diene monomer (EPDM)/barium titanate (BaTiO3)/mica (or graphite) composites with different volume fraction of mica (or graphite) were prepared by two-roll milling process. Thermal conductivity, crosslink density, cure, rheological, mechanical and dielectrical properties of composites were investigated. The results of rheological properties indicated that the 15Â vol% mica made the complex viscosity of EPDM/BaTiO3 compound to become non-sensitive to varying shear. In terms of mechanical properties, only 5Â vol% graphite flakes remarkably improved the tensile strength of EPDM/BaTiO3 (70/30) from 7.47Â MPa to 13.20Â MPa (76% increase). By comparison, the 20Â vol% mica just increased the tensile strength of EPDM/BaTiO3 (70/30) to 12.10Â MPa. In addition, 20Â vol% graphite flakes boosted the thermal conductivity and dielectric constant of EPDM/BaTiO3 (70/30) from 0.323Â WÂ mâ1Â Kâ1 and 7.1Â at 40Â MHz to 2.421Â WÂ mâ1Â Kâ1 (749% increase) and 70Â at 40Â MHz (almost 1000% increase), respectively. The excellent electric and thermal performance was attributed to the mobile Ï electrons in graphite flakes.
