[https://www.youtube.com/watch?v=GbT-pUsn5KU The Microwave Production of Expanded Graphite] - Using a microwave to expand graphite produces partially-exfoliated graphene "worms" that are useful in the production of graphene and for making supercapacitor batteries. This method involves microwaving acid-treated graphite to produce expanded graphite. Acid-treated graphite can be made by soaking approximately 10 grams of ~35 mesh flake graphite in 150 mL concentrated sulfuric acid (H2SO4, 98%) together with 50 mL 70% Phosphoric acid (70%) overnight. The acid molecules are small enough to squeeze in between and intercalate the layers of graphene that make up the graphite flakes. The graphite is then placed in a acid-resistant filter paper (PE/PTFE) and washed with copious amounts of deionized (DI) or distilled water several times to remove any excess acid until the pH reaches 7 and is dried overnight or for several hours in a vacuum drier at 60-80 degrees C. The dried acid-treated graphite is then placed in a modified domestic 1000-Watt microwave oven for 1-2 minutes at a time with frequent intermissions in order to remove the expanded graphite and to rearrange the remaining unexpanded graphite. The process is repeated until all the acid-treated graphite is expanded.

If you want to use this stuff for supercapacitors, you will need to heat treat it to make it more conductive
