제목 Effect of the silica particles on the electrical conductivity and thermomechanical property of epoxy/silver nanoparticles composite
초록 In this study, novel approach to decrease the contact resistance and coefficient of thermal expansion(CTE) of epoxy/Ag nanocomposites using silica particles has been introduced. Silver nanoparticles used as conductive fillers were replaced with silica particles because silica has been known to control the rheology of organic/inorganic hybrids and the reinforcement of polymer matrices. This study described herein concerns the effect of silica concentration and silica particle size on electrical resistivity, rheological property and thermomechanical property such as CTE of epoxy/Ag nanocomposites. In the electrical conductivity, epoxy/Ag nanocomposite with 18vol% Ag nanoparticles shows 4.7×10-4Ωcm after addition of 12vol% silica particles to this nanocomposite. In the thermomechanical study, silica-added the epoxy/silver nanoparticles composite, CTE of nanocomposites was decreased to 32.9 ㎛/m℃.
