Graphene Balloons Show Their Colors

Researchers from the Graphene Flagship have found a new potential application for graphene: mechanical pixels. By applying a pressure difference across graphene membranes, the perceived color of the graphene can be shifted continuously from red to blue. This effect could be exploited for use as colored pixels in e-readers and other low-powered screens. The research was a collaborative effort from researchers at TU Delft, Netherlands, and Graphenea, Spain, and the study has recently been published in the journal Nano Letters.

Graphene Flagship
Bringing together 118 academic and industrial partners in 12 research and innovation projects and 1 coordination and support project, the Graphene Flagship initiative will continue to advance Europe’s strategic autonomy in technologies that rely on graphene and other 2D materials. The initiative, which builds on the previous 10-years of the Graphene Flagship, is funded by the European Commission’s Horizon Europe research and innovation programme. The 2D-Experimental Pilot Line, addressing the challenges of upscaling 2D material production processes for the semiconductor industry, is another key component of the Graphene Flagship eco-system.
