Graphene technology for innovation in coatings and composites
costs - Improve performance, such as crack-resistance - Withstand wide temperature variations - Provide electrical conductivity for lightning strike protection and EMI shielding of electronic components Graphene Composites Example of applications: Aerospace and automotive
PROTECTIVE COATING FOR GRAPHITE ELECTRODES
• excellent electrical conductivity • abrasion resistance • no negative influence on steel. The aluminium layer of the protective coating melts at a relatively low temperature – at about 600 °C. It thus remains on the graphite surface as a liquid film with a constant thickness, guaranteeing
Graphite: A Multifunctional Additive for Paint and Coatings
Flexible Graphite Chemically inert Electrical conductivity Contact resistance Thermal conductivity Thin Lower Cost Proven performance Strength Not as thin as metals Graphite-Filled Polymers Known fabrication techniques Molded-in flow fields Low Density Thermal conductivity Electrical conductivity Temperature capability Brittleness
Next Generation Bipolar Plates for Automotive PEM Fuel Cells
The electrical resistance is reduced (and hence conductivity increased) by the application of coating. Laboratory tests have shown the coating itself to have an electrical resistance of 14.50-22.00μ ohm cm against that of graphite of 600-1000μ ohm cm.
