SILICONES & EPOXIDES

circuitboard.png

Addition of nanodiamond to silicone and epoxide materials can create polymer composites with significantly improved properties.  The changes are due in part to the numerically high mechanical and thermal properties of diamond, and in part due to nanoscale effects obtained by dispersing small particles into the polymer material.  The surface functionalisation of the nanodiamond particles means they will interact with the polymer molecules, as well as any other filler materials present.  Particularly in the case of polymers containing fillers, the modification in properties is very high, even when extremely low amounts of nanodiamond are added.

Typical Silicone-Nanodiamond applications:

  • Increasing thermal conductivity of thermal interface materials in combination with other fillers, without affecting electrical isolation
  • Increasing abrasion resistance
  • Extending both the high and low temperature limits of operation
  • Other properties still being explored

Nanodiamond may be added as a powder, using high shear and/ or ultrasonic dispersion, by pre-milling the nanodiamond together with other fillers, or via a compatible solvent borne dispersion.

Typical Epoxy-Nanodiamond applications:

  • Increasing thermal conductivity of thermal interface materials in combination with other fillers, without affecting electrical isolation
  • Increasing the strength of adhesives
  • Increasing abrasion resistance of coatings and composite components
  • Improving the impact resistance of composite panels
  • Extending both the high and low temperature limits of operation
  • Other properties still being explored

Nanodiamond may be added as a powder, using high shear and/ or ultrasonic dispersion, by pre-milling the nanodiamond together with other fillers, or via a compatible solvent borne dispersion.
