Silver Particles on the Thermal and Electrical Characteristics of ECAs

Abstract

This study presents information on the thermal and electrical characteristics of silver (Ag) in range size of 2–3.5 μm and 80 nm in diameter. The present method demonstrates the thermal conductivity analysis and electrical resistivity influence by various particle content of Ag in Epoxy matrix for both micro and nano-sized. Furthermore, new technique of thermal properties and electrical resistivity observation is proposed by hybrid-sized analysis to characterize the effect of Ag size. The proposed hybrid-sized technique uses micro- and nano-sized particle ratios to generate the composite. The thermal and electrical resistivity characteristics of the epoxy composite-filled micro-, nano-, and hybrid-sized Ag particle are correlated with their morphology. The thermal conductivity of the electrically conductive adhesive sample is affected by Ag particle size. The micro-sized Ag particle is better filler than the nano-size Ag particle in increasing performance of the thermal conductivity in the matrix epoxy. The results of the electrical resistivity of micro- and nano-particles demonstrated similar characteristics that transition within insulator into conduction occurred at 6 vol%. While hybrid-sized systems shown decreasing in thermal conductivity performance when decreasing number micro-sized ratio. Other observation in hybrid-sized presented that the better performance of electrical conductivity has shown at 50:50 weight ratio.
