Eco-friendly polymer nanocomposite coatings for advanced electromagnetic interference( EMI) shielding applications
Research Project
Proof-of-concept
Challenge
Electromagnetic waves( EMWs) from electronic devices can disrupt the functioning of nearby devices. EMI shielding is crucial for defence, communication, stealth and detection. Traditional metals, like copper and aluminium, provide shielding but are impractical due to their high density, cost, corrosion susceptibility and difficult processability. This is driving demand for alternatives.
Solution
This work uses easily scalable emulsion polymerisation methods to produce hybrid paints. These paints can be easily sprayed or brush-coated onto substrates with tuneable thickness. Combining various nanofillers, the project develops unique hybrid coatings with controlled nanofiller arrangement. These coatings, capable of multiband electromagnetic wave attenuation through synergistic dielectric and magnetic losses, address current EMI shielding challenges while providing flexibility, scalability and environmental compatibility
