Rice University researchers test 3-D carbon nanostructures’ thermal transport abilities

HOUSTON – (Nov. 2, 2017) – Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, according to Rice University engineers.

Rice materials scientist Rouzbeh Shahsavari and alumnus Navid Sakhavand first built atom-level computer models of pillared graphene — sheets of graphene connected by covalently bonded carbon nanotubes — to discover their strength and electrical properties as well as their thermal conductivity.

In a new study, they found that manipulating the joints between the nanotubes and graphene has a significant impact on the material’s ability to direct heat. That could be important as electronic devices shrink and require more sophisticated heat sinks.

The research appears in the American Chemical Society journal ACS Applied Materials and Interfaces.
