Abstract High thermal-conductivity coatings have garnered much attention in fields such as the automotive and aerospace industries. Commonly used filler-loaded coatings are limited either by the high viscosity of the coating paint or by the intrinsic properties of the filler. In this study, we used graphene as a high thermal conductivity filler to enhance the properties of paint used in the automotive industry. The effects of filler size on the thermal conductivity and viscosity of stable liquid dispersion (paint) are studied and modeled in graphene nanoplatelet-loaded paint (2.47 vol%), which exhibits enhanced thermal conductivity of 160% (1.6 vs. 0.6 W (m K)−1 for the neat commercial paint) and low viscosity. Furthermore, the filler with the optimum performance (in the paint) is studied in solid state, where it elicits a 720% enhancement in thermal conductivity (14.4 vol%).

提高石墨烯负载涂料的导热性：相变、流变学和填料尺寸的影响

摘要 高导热涂料在汽车、航空航天等领域受到广泛关注。常用的填料涂层受到涂料涂料的高粘度或填料的固有特性的限制。在这项研究中，我们使用石墨烯作为高导热填料来增强汽车工业中使用的涂料的性能。在石墨烯纳米片负载涂料 (2.47 vol%) 中研究并模拟了填料尺寸对稳定液体分散体（涂料）的热导率和粘度的影响，该涂料的热导率提高了 160%（1.6 对 0.6 W（m K)-1 用于纯商业涂料）和低粘度。此外，在固态下研究了具有最佳性能（在油漆中）的填料，
