A material for producing a conductive composition comprising polymer particles, conductive particles, and a liquid medium. The material is in a liquid/dispersion form until it is cured at which time it forms an electrically conductive composition. The composition contains larger sized polymer particles along with smaller metal conductive filler particles such as nanoparticle-sized filler particles. The larger polymer particles create excluded volume in the material matrix and reduce the percolation threshold of the conductive filler particles to provide a conductive material with a reduced volume fraction of electrically conductive filler. The electrical conductivity of the material is further increased after heat treatment which causes the conductive filler particles to sinter together to form a highly conductive network.
