Carbon nanoparticle infused optical mount
A passive thermal heat-pipe material comprising an optical mounting structure including heat producing electronic components is provided. Each structural component of the optical mounting structure may be at least partially comprised of a polymer including a plurality of carbon nanoparticles. In a further aspect, a method of creating an optical structure adapted to support a plurality of heat emitting components is provided. The method includes adding a percentage by concentration of carbon nanoparticles to a polymer base material, mixing the polymer base material and carbon nanoparticles uniformly, melting the mixture at high temperature, forming the melted mixture into a component of the optical structure, and cooling the formed component to solidify the component. The percentage may be between 2 and 10 percent.
