In October 2013, Carbodeon announced data on thermal materials. The company replaced 0.1-wt% precision nano-diamond material with boron nitride (45 wt.%), which has the highest thermal conductivity. Can increase thermal conductivity by 25%. The processing of the latest finishing grades of nanodiamond materials and composites provides similar performance improvements, but the use of nanodiamonds is reduced by more than 70%, so the cost is reduced.
The experimental samples were produced at the VTT Technology Research Center in Finland, and the thermal performance was analyzed in ESK (3M), Germany.
“The improved thermal conductivity of the material is due to the ultra-high thermal conductivity of the diamond. We optimize the performance of diamonds and other thermally conductive materials. Carbodeon can control the nano-diamond-filled polymer,†Carbodeon Chief Technology Official Vesa Myllymäki said. “Having the control over all product sizes, the core of nanotechnology – 'get more with less' can be fully realized.â€
Explosive synthetic nanodiamonds with a diameter of 4-6 nanometers often have problems with their surface properties due to their potential properties. Carbodeon uses its surface chemistry so that the particles can be dispersed and fused into the parent material, especially the polymer. As a result, the best properties of diamond will have little impact on other materials, making it more economical and more concentrated.
In order to achieve the required requirements, the thermal conductivity is increased to 100%, and the thermally conductive filler material is 20% nanodiamond.
"The realization of increased thermal conductivity does not affect the insulation properties or other mechanical properties of the material, nor does it reduce the degree of tool wear, making it more widely used in electronics and LEDs," said Vesa Myllymäki.
“In terms of metal finishing and industrial polymeric coatings for polymer composites, the thermal conductivity of Carbodeon nanodiamonds, and the continuation of our focus on application, we are not doing the best,†Myllymäki added. “We have recently obtained patents for thermal plastics composites containing nanodiamonds and will foresee the broad application prospects of these materials.â€

Carbodeon is a Finnish-based manufacturer of functionalized nanodiamond materials. In order to achieve 45% of the thermal conductivity of the material, by increasing the 0.03wt.% nanodiamond, the thermal conductivity of the polymer is improved by 20%. Compared with the conventional heat conductive materials, the cost is reduced and the thermal conductivity is increased.
