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.
