The fabrication and properties of Ag/Ni nanocomposite fluid.
In this article, an arc-submerged nanofluid synthesis system is proposed and developed for Ag/Ni nanocomposite fluid fabrication. In the fabrication process, the positive electrode uses an Ag rod and the negative electrode uses a Ni rod, with the two electrodes processed in the dielectric liquid. The nanocomposite fluid generated by the synthesis system is analyzed by morphological analysis, heat transfer analysis, magnetic analysis and the UV-Vis spectrophotometer optical property analysis. Experimental results show that the Ag/Ni nanocomposite fluid has a very high Zeta potential of 45 mV, so that without dispersant it can remain stabile longer than five months. Testing the Ag/Ni nancomposite fluid magnetism by SQUID, shows that paramagnetism appears in the nanocomposite fluid. Moreover, the Ag/Ni nanocomposite fluid preserves both the nickel's magnetic characteristic and silver's absorption capability to visible light.
