Researchers have developed a unique single-step process to achieve three-dimensional (3D) texturing of graphene and graphite. Using a commercially available thermally activated shape-memory polymer substrate, this 3D texturing, or 'crumpling', allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.
