This paper uses electrophoretic deposition for coating a self-fabricated CuO nanofluid on a stainless steel substrate and measures the nature of this nanofilm. The pH value of the fabricated CuO nanofluid is 6.0, with a highly consistent mean particle size of 30nm. This paper investigates the effects of the CuO nanofluid’s concentration, depositing time, voltage and sintering temperature on nanofilm, and also measures the micro-hardness of this CuO nanofilm and its UV-Vis absorption spectrum. The experimental results show that with voltage of 230V, depositing time of 5 minutes and sintering temperature of 200 ℃, we can acquire a CuO nanofilm of good compactness with micro-hardness higher then Hv110. Moreover, when the wavelength of illumination light is at the range of 400 nm ~ 700 nm, the CuO nanofilm has greater light absorbance, and the absorbance intensity grows stronger with the increase of depositing time.
