Plasma Treatment of Nanoparticles for

Plasma treatment of nanoparticles for nanofluids can be obtained by plasma treatment using low-temperature plasmas. The diamond nanoparticle surfaces, for example, can be modified by the low-temperature plasmas of methane and oxygen mixtures, which can improve their dispersion characteristics including dispersibility and suspension stability in water for nanofluid. Plasma treatment of diamond nanoparticles with selected plasma chemistry imparted various functional groups on the particle surfaces and tailored...
