Abstract

In one embodiment the present invention provides for a high thermal conductivity resin that comprises a host resin matrix 32 a high thermal conductivity filler 30. The high thermal conductivity filler forms a continuous organic-inorganic composite with the host resin matrix, and the fillers have an aspect ratio of between 3-100. The fillers are substantially evenly distributed through the host resin matrix, and are aligned in essentially the same direction. In some embodiments the resins are highly structured resin types.

Claims (37)
