  • Effect of Chemical Factors on Interfacial Electrical Resistivity Between Flexible Electrically Conductive Adhesives and Metal Electrodes

抄録

The effect of the chemical factors on electrical resistivity and interfacial electrical resistivity between silver-plated aluminum filled electrically conductive adhesives composed of polyhydroxyurethane-based binders and metal electrodes was investigated. Three types of polyhydroxyurethanes having different average molecular weights were used for the adhesives. The effect of the isocyanate cross-linker on the electrical resistivity differs depending on the difference in the average molecular weight in the binders. The interfacial electrical resistivity was increased by decreasing the molecular weight of the polyurethane binder. In addition, the isocyanate cross-linker was found to affect the interfacial electrical resistivity with copper electrodes. These results suggest that the binder chemistry of flexible electrically conductive adhesives influence both of electrical resistivity and interfacial electrical resistivity with metal electrodes.
