The DOE is investigating new technologies for high performance, low cost heat exchangers. One way to achieve this goal is to develop improved heat transfer fluids using nanotechnology. Nanofluids are metallic nanoparticles (10 -100 nm) that increase overall thermal conductivity when dispersed in typical coolants such as water or ethylene glycol. The greatest challenge in commercializing nanofluids is the stability of the `metallic nanoparticles¿ in the base coolant over long periods of time. This project will develop a self-assembled monolayer coating for metallic nanoparticles that will improve the dispersion and stability of nanoparticles in nanofluid coolants. The main benefit of using self-assembled monolayers is the durability of the coating, as the monolayer is formed by chemical reaction of the monolayer with the metal particles. The covalent bonding results in a permanent bond that does not dissolve in solution. Commercial Applications and other Benefits as described by the awardee: The nanofluids stabilization technology should benefit many industrial and commercial applications where the working fluid limits overall performance. These applications include building HVAC, automobile radiators, and high performance electronics applications. The nanofluids also will help reduce fossil fuel usage and resulting green house gas emissions.
