In microscopic images, the foam dubbed "GO-0.5BN" looks like a nanoscale building, with floors and walls that reinforce each other. The structure consists of a pair of two-dimensional materials: floors and walls of graphene oxide that self-assemble with the assistance of hexagonal boron nitride platelets.
The researchers say the foam could find use in structural components, as supercapacitor and battery electrodes and for gas absorption, among other applications.
The research by an international collaboration led by the
Samples the size of a pencil's eraser were compressed with one or two pennies to see how well they would bounce back.
The h-BN platelets connect to graphene oxide and absorb stress from compression and stretching, preventing the GO floors from crumbling and significantly enhancing the material's thermal stability, Vinod said. The platelets also prevented the propagation of cracks that destroyed samples with less or no h-BN.
