Recent work has demonstrated that while nanofluids do indeed exhibit increased heat transfer properties , there is no abnormal enhancement as had been claimed by early proponents of nanofluids. However, this lack of abnormal enhancement of material properties does not discount the usefulness of nanofluids, but it does challenge us to decrease the currently high cost of nanoparticle synthesis and treatment methods. Surfactants, traditionally used to prevent agglomeration and promote dispersion, have significant shortcoming with respect to thermal stability, required for nanofluids. Surface functionalization treatments have shown a high level of success, but the methods proposed are either too costly or difficult to scale up. Photo-induced chemical vapor deposition (photoCVD) shows promise as a scalable method for nanoparticle treatment. This talk will present an overview of scalable gas phase methods and focus on the use of photoCVD for the low-cost treatment of nanoparticles required for nanofluid and nanocomposite synthesis.
