Energy related processes, such as energy storage and catalysis typically utilize high surface area electrodes that possess macro- and micropores like carbon aerogels (CAs). Traditional CA synthesis results in isotropic, random nanoporous networks that work well for applications relying on diffusional mass transport. However, many other applications would benefit from integration of engineered macroporous network structures that enable fast charge-transport kinetics. Our work focuses on 3D printing these aerogels via direct ink writing (DIW) to precisely deposit inks in a pre-defined tool path to form 3D structures to improve both mass transport and output power efficiency for electro-chemical applications. We have also demonstrated that by using 3D printed graphene aerogels as scaffold, we can support ultrahigh mass loadings of pseudocapacitive materials. Apart from DIW, 3D-printed sacrificial polymeric templates were used to generate templated CAs with integrated engineered nonrandom macroporous network structures.
