Microwave dielectric constants of composite samples made by high dielectric constant ceramic filler dispersed in the polyethylene matrix are studied in this article. The filler material of strontium titanate ceramic has a dielectric constant of 300 at microwave frequencies. The logarithmic and exponential mixture equations and a newly published mixture equation were adopted in this study. The matching...
Zinc dimethacrylate functionalized graphene (Z‐GE), as reinforcing nanofiller for natural rubber (NR), was synthesized by liquid‐phase exfoliation and in situ method. The morphology and structure of Z‐GE were characterized to confirm the exfoliation and functionalization of GE. The NR/Z‐GE composites were prepared and investigated by mechanical analysis, crosslinked network analysis and the analysis...
The microwave dielectric properties of binary composites made by high dielectric constant ceramic fillers and polyethylene matrix are studied in this paper. Three ceramic powders of fillers with dielectric constants of 100 and 170, respectively, are adopted. The experimental dielectric constants of ceramic dispersions in the polyethylene matrix at microwave frequencies of 5 to 10 GHz are compared...
The microwave dielectric constant of strontium titanate ceramic dispersed in the polyethylene matrix is studied by powder mixture equations in this article. The experimental dielectric constant values of the mixtures are compared to the theoretical curves of five published mixing rules. A new empirical mixture equation is proposed. The dielectric constant of pure strontium titanate is then estimated...
