Ceramic Aerogel Composite

Atomic layer deposition grows thin film layers of materials using sequential exposure of a substrate to gas molecules. Researchers at Purdue University are using a graphene aerogel substrate and depositing thin layers of aluminum oxide ceramic to create a new material that is light, elastic, strong, conductive, and offers thermal insulation. This has excellent potential for new forms of electronic components.

A new featherweight, flame-resistant and super-elastic “metamaterial” has been shown to combine high strength with electrical conductivity and thermal insulation, suggesting potential applications from buildings to aerospace.
The composite combines nanolayers of a ceramic called aluminum oxide with graphene, which is an extremely thin sheet of carbon. Although both the ceramic and graphene are brittle, the new metamaterial has a honeycomb microstructure that provides super-elasticity and structural robustness. Metamaterials are engineered with features, patterns or elements on the scale of nanometers, or billionths of a meter, providing new properties for various potential applications.
