Dielectric constant, power factor, and conductivity of the system rubber-calcium carbonate

Abstract: The dielectric constants and power factors of mixtures of calcium carbonate with Vistanex and with natural rubber were determined at 1 and 100 kilocycles per second. There was little difference between the values at the two frequenciel'. Two different formulas were found to express the dielectric constants of the mixtures as functions of the dielectric constants of the respective components. The dielectric constant of the pure calcium carbonate employed was determined by the method of liquid mixtures. The powe… Show more

“…For nanocomposites containing CaCO3, the above assertion implies that the aforementioned permittivity effects are less pronounced, such that nanocomposites containing CaCO3 exhibit higher AC breakdown strengths than systems containing equivalent amounts of MgAl2O4. However, the permittivity of bulk CaCO3 (ε' = 8.8 [38]) is not markedly different from that of bulk MgAl2O4 (ε' = 8.4 [37]), while the measured permittivity of nanocomposites based on the former nanofiller is consistently lower than the measured permittivity of nanocomposites based on the latter (see Figure 7). While it could be inferred from this that the nanofiller dispersion of CaCO3 is generally better than in the case of MgAl2O4, the SEM micrographs in Figure 6 provide no compelling evidence for this.…”
