DOE Total Funding: $149,998
Project Term: July 2, 2018 – April 1, 2019
Grant Type: SBIR


In this project, Tetramer Technologies will prepare bi-layered reduced graphene oxide (rGO) films using a dispersion-by-exfoliation technique previously developed by the subcontractor, Clemson University.  These films will be further compounded with a variety of polymer layers to produce new materials competitive with conventional indium-tin oxide (ITO) films. Extensive characterization and testing of these intermediate materials will be used to establish the necessary Phase I proof of principle. Further optimization and manufacturing methods development would be completed in Phase II.


The resulting composite material is expected to be more transparent, flexible, conductive, and stable than ITO and other known candidate replacement materials. The new method of reduced graphene oxide production represents a significant and cost-effective departure from traditional methods of production and is expected to result in transparent conductive oxides that can be used as anodes in the manufacture of contemporary OLEDs that would be competitive in both optical and electrical performance at a cost advantage compared to those using ITO films.
