Study on the Mechanical Property of Cu-Filled Isotropically Conductive Adhesive/SiO₂ Composites

Abstract:

Cu-filled isotropically conductive adhesive/SiO₂composites were prepared by direct-blending modified SiO₂ into Cu-filled ICAs. The effects of different contents of SiO₂ on the mechanical property were sdudied in this paper. The infrared spectra of the cured product between epoxy resin and imidazole was obtained with FT-IR. The surface morphology of the composite and its fractured surface after tensil test were observed by scanning electron microscope(SEM). In addition, energy dispersive spectrometry(EDS) was applied to analyze the distribution of Si in the adhesive layer. Experimental results showed that a small amount of SiO₂ powders could evenly distribute in the Cu-filled ICAs, and as a reslut the mechanical property of Cu-filled ICA/SiO₂ increased dramatically with the addition of SiO₂. The best shear strength of the composite could reach up to 16.1MPa and 36.4% higher than the ICAs without addition SiO₂ when the content of SiO₂ was 3%.
