Abstract:
      The morphology of silver fillers, surface lubricants of silver fillers, the composition of matrix, curing procedures and so on will affect the performance of ECAs. The morphology of silver fillers is a crucial factor. Effect of the silver with different morphologies on properties of ECAs under the same condition was studied. silver flakes, silver spheres and silver wires were prepared and treated by glutaric acid to eliminate the effect of other factors. Then these silver particles were used as conductive fillers compositing with epoxy resin to prepare ECAs. The thermal degradation, electrical conductive properties, mechanical property and storage stability of ECAs were investigated. The results show ECAs filled with silver wires exhibit lowest electrical resistivity and percolation threshold, best mechanical property and good storage stability under the same condition. ECAs filled with silver flakes show better electrical conductive property and storage stability but poorer mechanical property than ECAs filled with silver spheres.
