开发了新型复合碳颗粒，其可以在没有粘合剂的情况下自组装为基底上的涂层。这些碳颗粒被用作涂层，以提高散热和它们的导热系数，表面发射率和冷却性能进行了测量。同时具有硫醇和环氧官能团的碳颗粒在没有粘合剂的情况下自组装在散热器表面形成涂层，这大大提高了涂层的热导率。用碳颗粒涂覆散热器产生了比在传统方法中添加粘合剂所获得的更高的热导率和发射率，并且显著增强了冷却性能。此外，碳纳米管的冷却性能优于所有其他粒子时，涂覆在基板上，因为它具有最高的导热性和良好的辐射发射率。我们开发了一个方程来描述影响散热涂层的冷却性能的各种参数。该方程得到了实验数据的证实。
Novel composite carbon particles are developed that can self-assemble as a coating on a substrate without a binder. These carbon particles were used as a coating to enhance thermal dissipation and their thermal conductivity, surface emissivity and cooling performance were measured. Carbon particles with both thiol and epoxy functional groups self-assembled to form a coating on the surface of a heat sink without a binder, which greatly improved the thermal conductivity of the coating. Coating a heat sink with the carbon particles yielded a higher thermal conductivity and emissivity than could be obtained with the addition of binder in the conventional approach, and significantly enhanced the cooling performance. In addition, the cooling performance of the carbon nanotube outperformed all other particles when coated on a substrate, because it had the highest thermal conductivity and good radiation emissivity. We developed an equation to describe the various parameters affecting the cooling performance of the thermally dissipative coating. This equation was confirmed by the experimental data.
