The Fabrication of Epoxy-nanoclay composite and electrical properties

Epoxy-nanoclay composite 제작과 전기적 특성

Nanocomposites of a epoxy resin are synthesized and evaluated. the present study investigated the effect of nanoclay additives on the properties of diglycidyl ether or bisphenol A(DGEBA) epoxy resin. DGEBA was mixed with 3$\sim$7 wt% organically modified layered silicate, Cloisite 30B for three hours. The average grain size of the specimens decreased with adding Cloisite 30B. The dielectric constant showed between 3.2$\sim$3.5 and the dielectric loss showed between 3.2$\sim$5.7 % in all specimens. Dielectric strength showed a best valu of 20.8 kV/mm at added with Cloisite 30B 5 wt%.
