Effect Of Hybridization On The Functional Properties Of AgMF–MWCNT-Filled Electrically Conductive Adhesive

A combination of metal and non-metal filler in an epoxy resin, called a hybrid electrically conductive adhesive (ECA), is an important development in the field of highly conductive electronic interconnect materials. Carbon nanotubes (CNTs) are well known for contributing strength and stiffness to EC...
