The Properties and Application of Epoxy/Clay Nanocomposites in the Copper-Ciad Laminar

Abstract

Epoxy/Clay nanocomposites have been prepared by exfoliating the modified clays, which are intercalated with the amine functional group, in an epoxy resin. Exfoliation of the clay within the cross-linked epoxy matrix was verified by using X-ray diffraction and transmission electron microscopy. The Epoxy/Clay nanocomposites are applied to prepare epoxy copper-clad laminar, relatively higher thermal stability, lower coefficient of thermal expansion, and water absorption were observed when they compared with FR-4 laminar without clay existed.
