Permittivities of the Carbon Nano Fiber/Epoxy Composite According to the Dispersion Methods

분산 방법에 따른 카본 나노 섬유/에폭시 복합재료의 유전율

This paper presents a study on the permittivities of the carbon nano fiber/epoxy composite at microwave frequency. The permittivities of composite materials depend on the concentrations and the dispersion methods of the carbon nano fibers. The experimental values of complex permittivities were obtained for the specimen made by dispersion method using ethyl alcohol as dispersion media and compared with the results by simple mechanical mixing method.
