Incorporation of silver nanoparticles coated with mercaptosuccinic acid/poly(ethylene glycol) copolymer into epoxy for enhancement of dielectric properties

► Novel route to the synthesis of MSA/PEG copolymer-coated silver nanoparticles developed. ► The size of silver nanoparticles is successfully controlled use different copolymer. ► Developed silver-epoxy nanocomposites exhibit huge increase in dielectric constant.
