Method 3: DVD burner - LightScribe technology approachTo make graphene using this method, the recipe calls for a DVD computer drive with LightScribe technology as well as some graphite oxide. You may obtain graphite oxide from a manufacturer, or you can make some graphite oxide at home for this experiment. If you want to find out how to make graphite oxide at home, scroll down to the next sectionGraphite oxide is water-soluble, so after mixing it with water, carefully pour it on a DVD disc. Make sure that the graphite oxide solution is evenly distributed on the plastic surface of the disc. After the solution has dried and created a film of graphite oxide on the disc, place the disc into the DVD drive, film-side down. Use the LightScribe software to burn in the layer of oxide. The areas of the film which come into contact with the laser beam will be turned into graphene. The laser beam causes a chemical reduction which reduces graphite oxide to graphene. The resulting graphene layer should be carefully removed from the disc and cut into appropriate sized pieces. These pieces can be used directly to create a graphene supercapacitor! This is perhaps the easiest way to make graphene at home, but it assumes that you have access to graphite oxide and a Laserscribe drive.One reader suggested that the LightScribe DVD laser can be replaced using a simple Xenon flash. If you have a photo-flash, you could try this approach as well, and report the results to us at "contact at our site domain". Another tip: do NOT do this if you are not comfortable with voiding the warranty of the DVD burner.
