Roll-to-roll patterning of transparent and metallic layers
Systems and methods are disclosed by which patterns of various materials can be formed on flexible substrates by a continuous roll-to-roll manufacturing process. The patterns may include metallic, transparent conductive, or non-metallic elements with lateral dimensions including in the range from below 100 nanometers to millimeters and with thickness dimensions including the range from tens of Angstroms to greater than 10,000 Angstroms. The substrate may be any material capable of sufficient flexibility for compatibility with roll-based processing equipment, including polymeric films, metallic foils, and thin glass, with polymeric films representing a particularly broad field of application. Methods may include the continuous roll-to-roll formation of a temporary polymeric structure with selected areas open to the underlying substrate, the continuous addition or subtraction of constituent materials, and the continuous removal, where necessary, of the polymeric structure and any excess material.
Methods, apparatus, and systems for fabricating solution-based conductive 2D and 3D electronic circuits
This work develops a novel microfluidic method to fabricate conductive graphene-based 3D micro-electronic circuits on any solid substrate including, Teflon, Delrin, silicon wafer, glass, metal or biodegradable/non-biodegradable polymer-based, 3D microstructured, flexible films. It was demonstrated that this novel method can be universally applied to many different natural or synthetic polymer-based films or any other solid substrates with proper pattern to create graphene-based conductive electronic circuits. This approach also enables fabrication of 3D circuits of flexible electronic films or solid substrates. It is a green process preventing the need for expensive and harsh postprocessing requirements for other fabrication methods such as ink-jet printing or photolithography. We reported that it is possible to fill the pattern channels with different dimensions as low as 10?10 ?m. The graphene nanoplatelet solution with a concentration of 60 mg/mL in 70% ethanol, pre-annealed at 75? C. for 3 h, provided ?0.5-2 kOhm resistance. The filling of the pattern channels with this solution at a flow rate of 100 ?L/min created a continuous conductive graphene pattern on flexible polymeric films. The amount of graphene used to coat 1 cm.sup.2 of area is estimated as ?10 ?g. A second method regarding the transfer of graphene material-based circuits with small features size (5 ?m depth, 10 ?m width) from any solid surface to flexible polymeric films via polymer solvent casting approach was demonstrated. This method is applicable to any natural/synthetic polymer and their respective organic/inorganic solvents.
