Influence of Silver / CNTs on Epoxide Resin Based Conductive Adhesive

Abstract:

Article Preview

Silver / CNTs was prepared by ball milling method and was used as filler to reinforce epoxide resin based conductive adhesive. The effect of content and dispersion state of the filler on tensile strength, tensile modulus, fracture extensibility and electrical resistance of the composites were studied. The results indicated that the filler could be dispersed well in epoxide resin matrix by ultrasonic method and the mechanical and electrical properties was improved greatly. The best content of the silver / CNTs was 0.75 wt% (considering of CNTs weight percentage), when the tensile strength, tensile modulus and fracture extensibility increased 42.6%, 18.8% and 115.3% respectively. With the increase of silver/CNTs, the conductivity of the matrix increased significantly. The micro structure analyses showed that the silver-covered CNTs worked as conductive channel and the electrons were easy to transfer through silver powder by CNTs network.
