(Closed) GEMIS – Graphene-enhanced Electro-Magnetic interference Shielding


Electromagnetic interference (EMI) is considered a potential and major source of operating problems to electronic devices, as well as a cause of its performance and lifetime reduction, especially in a world where electronic devices are increasingly ubiquitous. GEMIS aims to develop an advanced technological solution based on graphene liquid dispersions to address the issue of electromagnetic interference.

Current shielding materials used to protect electronic devices from EMI are based on heavy, brittle and expensive metals, while the major EMI applications have a huge demand for flexible, additive, light, and inexpensive materials. This is of crucial importance, for instance, for several vehicles industries, from hybrid and electrical cars to airplanes, where weight reduction is imperative to increase autonomy and reduce carbon footprint.

Graphene and its related materials are considered the most promising and effective candidates for effective EMI shielding because of their excellent electrical properties, extremely high specific surface area, and unprecedented strength to weight ratio.

Electronics (IT and sensors), telecommunications (space), aviation, naval and the Internet of Things are several sectors that will benefit from the advanced technological solution provided by the project.

Expected Outcomes

  • A universal formulation for a liquid dispersion of graphene materials with highly effective EMI shielding;
  • The consequent production of two EMI shielding composites based on polymers and epoxies;
  • Design and fabrication of a custom-made equipment to specifically apply the developed EMI shielding solutions on electric wires to be used in the automotive industry.
