We have demonstrated that electrical conductive paper can be produced by traditional roll-to-roll papermaking  as well as by wet moulding. The former allows for more efficient production where as the latter allows for more flexible production and the formation of 3D shaped materials. A key aspect of the production is the retention of the electrical conductive components. This is controlled by classical colloidal chemistry tuning the stability of the conductive particles and their interactions with the cellulosic fibers. To create a conductive paper material it becomes an intricate balance between processability, mechanical rigidity and electrical properties. Post processing, for example mechanical pressing, could also be utilized to boost electrical properties by enhancing the contact between the conductive particles within the paper fiber network.
