This Small Business Innovative Research Phase I project is to develop extremely high thermal conductivity heat sinks that are thermal expansion matched to advanced semiconductors for high performance electronic and electro-optical systems. With low cost natural graphite platelet reinforcement, CuGrp composite heat sinks with thermal conductivities ranging from 750 to 900 W/mK will be achieved while controlling thermal expansion over the range of 7 to 4 ppm/K respectively. These properties are a factor of 2 to 2.5 times Cu and exceed any CTE matched thermal management material available. This project will result in a family of high performance passive thermal management materials that will increase the performance of electronic and electro-optical systems without increasing complexity. These technologies will service an a $500mm market that is growing at a rate of 8.5%/year. Immediate applications will be heat spreaders for LED and laser diode manufacturers for advanced communication, industrial and municipal lighting and flat screen displays as well as heat spreaders for advanced radar MMIC and T/R modules. Because of the projected low cost, other expected applications include power control systems for advanced hybrid and electric powered vehicles as well high performance IGBT base plates.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

该小型企业创新研究第一阶段项目旨在开发具有极高导热性的散热器，其热膨胀与高性能电子和光电系统的先进半导体相匹配。采用低成本的天然石墨片增强体，将获得热导率在750至900 W/mK范围内的CuGrp复合热沉，同时将热膨胀分别控制在7至4 ppm/K范围内。这些性能是铜的2至2.5倍，超过了任何CTE匹配的热管理材料。该项目将产生一系列高性能被动热管理材料，这些材料将在不增加复杂性的情况下提高电子和光电系统的性能。这些技术将服务于一个5亿美元的市场，该市场以每年8.5%的速度增长。直接的应用将是LED和激光二极管制造商的散热器，用于先进的通信、工业和市政照明和平板显示器，以及先进的雷达MMIC和T/R模块的散热器。由于预计的低成本，其他预期的应用包括先进的混合动力和电动汽车的功率控制系统以及高性能IGBT基板。该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。
