Pin It

Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University.

The Rice lab of chemist James Tour set nanotubes into graphene in a way that not only mimics how steel rebar is used in concrete but also preserves and even improves the electrical and mechanical qualities of both.

The technique should make large, flexible, conductive and transparent sheets of graphene much easier to manipulate, which should be of interest to electronics manufacturers, Tour said. He suggested the new hybrid could, upon stacking in a few layers, be a cost-effective replacement for expensive indium tin oxide (ITO) now used in displays and solar cells.

The research appears this month in the American Chemical Society journal ACS Nano.
