Abstract

A method of graphitic petal synthesis includes a step of providing a flexible carbon substrate, such as that including carbon microfibers. The method further includes the step of subjecting flexible carbon substrate to microwave plasma enhanced chemical vapor deposition. The resulting synthesized graphitic petal structure may optionally be coated with PANI.
