Abstract
An interconnected corrugated carbon-based network comprising a plurality of expanded and interconnected carbon layers is disclosed. In one embodiment, each of the expanded and interconnected carbon layers is made up of at least one corrugated carbon sheet that is one atom thick. In another embodiment, each of the expanded and interconnected carbon layers is made up of a plurality of corrugated carbon sheets that are each one atom thick. The interconnected corrugated carbon-based network is characterized by a high surface area with highly tunable electrical conductivity and electrochemical properties.
Claims19
A method of producing a material comprising patterned interconnected corrugated carbon-based network, comprising:
- a. receiving a substrate having a carbon-based oxide film;
- b. irradiating the carbon-based oxide film with a light beam to reduce and expand portions of the carbon-based oxide film, thereby forming the material comprising a plurality of expanded and interconnected carbon layers that are electrically conductive;
- and
- c. selectively tuning the electrical conductivity of the material by one of:
- i. increasing a gray-scale level of the light beam, wherein increasing the gray-scale level of the light beam decreases a sheet resistance of the material;
- or
- ii. irradiating the carbon-based oxide film with the light beam two or more times, wherein each subsequent irradiation by the light beam decreases the sheet resistance of the material;
- wherein an oxygen content of the material is less than 5%.
