Abstract

A z-axis anisotropic electrically conducting polymer-matrix compositefilm was developed. It comprised 25 volume percent copper coated polyether sulfone particles and a polyimidesiloxane matrix. Each particle protruded from both sides of the film and provided a conducting path along the z-axis. A z-axis pressure of 40 kPa resulted in a z-axis electrical resistivity of 2 Ωcm for the overall film (i.e., 0.5 Ωcm.for a conducting path); subsequent pressure removal caused the resistivity to rise to 7 Ωcm only. The film exhibited negligible stress relaxation and a low modulus of 1.67 GPa.
