Nanoparticle materials can be very inexpensive and the technology for producing nanofluids is mature. The production of inks, paints, coatings, and suntan lotions is old enough to be a very competitive industry. So, nanofluids probably set the benchmark for cost-effective technologies. But can the same be said about nanofluids and reliability? The importance and the answer to this depend on the application. When inks, paints, coatings, and suntan lotions are no longer stable, the consequence may be very limited. However, the consequence of an unstable nanofluid for heat transfer equipment may be quite severe. Consequently, if nanofluids are to be used on a large scale in heat transfer equipment, significant research will be required to ensure system reliability.
