Application Spotlight: Graphene in EMI Shielding Coatings

📡 Why Graphene for EMI Shielding?

Electronic devices are becoming smaller and denser — increasing the risk of electromagnetic interference (EMI). Graphene, with its high aspect ratio and conductivity, is emerging as a powerful component in lightweight, flexible EMI shielding coatings.

⚙️ Advantages of Graphene EMI Formulations

• High conductivity at low filler content (1–3 wt%)

• Flexible film formation over plastic and metal substrates

• Easy to spray, print, or brush-apply

• Can be blended with silver, carbon black, or CNTs for hybrid shielding

💡 Test Results (Typical)

• Surface resistivity: <10 Ω/sq

• Shielding effectiveness: 20–30 dB @ 1–3 GHz

• Thermal stability: Up to 250°C depending on matrix

📦 Recommended Product: GR-RGO Dispersion

• Water-based, ready to use

• Good adhesion to epoxy, PU, acrylics

• Custom viscosity control
