Abstract
ABSTRACTThe thermal and surface properties of pure polysiloxane and graphite nanopowder (10% to 50%) reinforced polysiloxane composite films were studied. Polysiloxane/Graphite (50%-50%) Composite exhibit improved thermal conductivity (k – 0.35 W/mK) and decreased Junction temperature (ΔTj = 31.29 °C @ 700 mA) and thermal resistance (∆Rth-tot = 14.96 K/W @ 700 mA) compared to pure polysiloxane film. Overall, the prepared composites can be used as an alternate elastomer thermal pad or Thermal Interface Material for efficient thermal management in electronic packaging especially for LED applications.
