The broader impact/commercial potential of this I-Corps project is more efficient heat transfer in a variety of potential industrial and consumer electronics applications. More efficient heat transfer translates into greater computational speed and output. In a world where electronics are growing more powerful and are ever increasing in capacity, the ability to remove heat is a significant consideration. This platform technology has the potential to be integrated as a high performance thermal grease. One possible application is as a computer CPU grease (or heat paste, heat sink compound, heat sink paste, thermal compound, thermal gel, thermal interface material, or thermal paste). Similar products are commonly used as an interface between heat sinks and heat sources.This I-Corps project further develops a class of novel greases that incorporate nanoparticles to enhance their performance. Thesee are stable and homogeneous greases based on carbon nanotubes in polyalphaolefin oil. Inter molecular Van der Waals forces and three dimensional percolation networks in the grease structure are determined to be the stability of the grease. The work builds on a recent discovery of a way to significantly enhance the electrical and thermal conductivity of the grease by including these additional additives in small amounts.

这个I-Corps项目的更广泛的影响/商业潜力是在各种潜在的工业和消费电子应用中更有效的传热。更有效的传热转化为更大的计算速度和输出。在一个电子产品越来越强大，容量不断增加的世界里，散热能力是一个重要的考虑因素。该平台技术具有集成为高性能导热润滑脂的潜力。一种可能的应用是作为计算机CPU润滑脂（或热膏，散热器化合物，散热器膏，热化合物，热凝胶，热界面材料，或热膏）。类似的产品通常用作散热器和热源之间的接口。I-Corps项目进一步开发了一类新型润滑脂，其中包含纳米颗粒以提高其性能。这是一种稳定且均匀的基于碳纳米管的聚烯烃油润滑脂。油脂结构中的分子间范德华力和三维渗透网络决定了油脂的稳定性。这项工作建立在最近发现的一种方法的基础上，通过少量添加这些额外的添加剂，可以显著提高润滑脂的导电性和导热性。
