Interlaced random networks of heterogeneous, rigid rod like particles such as metallic nanowires and carbon nanotubes are formed by various methods. The resulting combination provides characteristics that are unique and not attainable by either of the individual components on their own. In one of the embodiments, such heterogeneous networks are continuously formed on a master hot roller surface by application of the rigid rod components from separate sources and the post formed network is transferred fully or partially onto a receptor surface of a moving web directly in-contact with the master surface. In another embodiment the heterogeneous networks are formed on the said master surface or hot roller by applying formulations that are co-stabilized dispersions of heterogeneous, rigid rod like particles in a common solvent. In yet another embodiment, such heterogeneous networks are formed by contacting the receptor surface with more than one such master surface or hot roller.
