Abstract
An aerogel film may be formed of graphene nanoribbon segments that are crosslinked together at their ends. The graphene nanoribbon segments may include a molecular backbone of aromatic rings or fused aromatic ring systems concatenated together in an approximately linear fashion. The rings or ring systems may be further fused together by bridges of atoms connecting adjacent aromatic rings or fused aromatic ring systems. Each bridge may include only a single atom or two atoms, for example, a sulfur atom, an oxygen atom, or a nitrogen atom, or combinations thereof.
