| Abstract | A microfluidic system for synthesizing Cu2O nanofluids was reported. The reaction between cupric-sulphate (CuSO4) and sodium-hydrate (NaOH) yielded cupric-hydroxide (Cu(OH)2) and sodium sulfate (Na2SO4). The cupric-hydroxide Cu(OH)2 quickly decomposed into cupric-oxide (CuO) and water (H2O) under some heating. The effect of fluid flow rates by setting the CuSO4 was examined at flow rate at 50, 75, 100, 125, 150, 200, 250, and 300 μL/min, respectively, and keeping the flow rate ratio of CuSO4, NaOH, and N2H4 fluids as 1:1:2. The results showed that the fluid was very stable, and no bulk phase separation was observed for all samples after 24 h of its preparation. The scanning electron microscope (SEM) images of nanoparticles showed that the particles could be changed from a spherical shape to a polyhedral by varying the CuSO4 concentration and/or fluid flow rates. | ||||
