    • The present invention relates to processes for preparing a stable suspension of carbon nanoparticles in a thermal transfer fluid to enhance thermal conductive properties, viscosity, and lubricity. One process is to disperse carbon nanoparticles directly into a thermal transfer fluid and other additives in the present of surfactants with intermittent ultrasonication. The second process is carried out in three stages. First, carbon nanoparticles are dispersed into a volatile solvent. Then, a thermal transfer fluid, surfactants, and other additives are added into this intermediate dispersion and mixed thoroughly. At last, the volatile solvent is removed to produce a uniformly dispersed nanofluid. The third process is to disperse carbon nanoparticles at an elevated temperature into a homogeneous mixture of surfactants and other additives in a thermal transfer fluid with help of a physical agitation. The present invention also relates to compositions of carbon nanoparticle nanofluids, such as nanolubricants and nanogreases. The nanofluid of the present invention is a dispersion of carbon nanoparticles, particularly carbon nanotubes, in a thermal transfer fluid in the present of surfactants. Addition of surfactants significantly increases the stability of nanoparticle dispersion. For nanogreases, carbon nanoparticles function both as a thickener to modulate viscosity and as a solid heat transfer medium to enhance thermal conductivity and high temperature resistance.
    • 本发明涉及制备碳纳米颗粒在热转移流体中的稳定悬浮液以提高导热性能,粘度和润滑性的方法。 一个过程是将碳纳米颗粒直接分散在表面活性剂的热传递流体和其它添加剂中,并间歇地进行超声波处理。 第二个过程分三个阶段进行。 首先,将碳纳米颗粒分散到挥发性溶剂中。 然后,将热转移流体,表面活性剂和其它添加剂加入到该中间体分散体中并充分混合。 最后,除去挥发性溶剂以产生均匀分散的纳米流体。 第三种方法是在高温下将碳纳米颗粒分散在热传导流体中的表面活性剂和其它添加剂的均匀混合物中,有助于物理搅拌。 本发明还涉及碳纳米颗粒纳米流体的组合物,例如纳诺润滑剂和纳米润滑剂。 本发明的纳米流体是在表面活性剂存在的热传递流体中的碳纳米颗粒,特别是碳纳米管的分散体。 表面活性剂的添加显着增加了纳米颗粒分散体的稳定性。 对于纳米颗粒,碳纳米颗粒既可用作增稠剂,也可用于调节粘度,并用作固体传热介质,以提高导热性和耐高温性。
