The second part was to test the appearance, ingredient analysis, surface potential, thermal conduction properties, and magnetism of the nano composite fluid prepared from the parameters. The experiment found that unoxidized particles, Ag, Cu, Fe, and Ni appeared round. If combined with oxygen in water as oxides, the nano particles would grow toward certain directions. In copper/iron nano composite fluid, FeO appeared cubic, Cu2O appeared coniferous. In silver/iron nano composite fluid, FeO was polygonal. In dielectric potential detection, the nano composite fluid was likely to aggregate and deposit, except for silver/iron set. In other sets, the pH of silver/cobalt nano composite fluid was 7, surface potential was 21.21mV; the pH for silver/nickel nano composite fluid was 6.5, surface potential was 21.04mV; the pH for copper/iron nano composite fluid was 7, surface potential was -30mV. The fluid particles of the three sets could all maintain suspension of 2 weeks or more. For thermal conduction, the silver/nickel, nano composite fluid showed the best thermal conduction. Under temperature of 30℃ fluid weight conduction of 0.4%, the thermal conduction increase was 26%. For magnetic detection, except for silver/iron nano composite fluid, the nano particles of other three sets were paramagnetic, and all four sets were soft magnetic nano composite materials.
