Provided is a method of forming a conductive polymer composite. The method includes forming a mixture. The mixture includes a first thermoplastic polymer, a second thermoplastic polymer and a plurality of metal particles. The first thermoplastic polymer and the second thermoplastic polymer are immiscible with each other. The plurality of metal particles include at least one metal that is immiscible with both the first thermoplastic polymer and the second thermoplastic polymer. The method includes heating the mixture to a temperature greater than or equal to a melting point of the metal.
