Fabrication of Superhydrophobic CuO Coating on Steel by Electrodeposition Modified with Stearic Acid

Dynamic Contact Angle and Corrosion Test Measurements on Cu and CuO-Stearic Acid Modifications on Steel Surfaces

“…The specimen preparation method followed the method published in literatures Brassard et al, 2015;Wen et al, 2018;Liu et al, 2015;Trisnanto et al, 2018). The steel metal was obtained from PT Santo Jaya Teknik.…”

“…After substrate was dried, the steel substrate was treated with alkali cleaning process to remove grease from the substrate surface. A solution containing of 30 g/L NaOH, 20 g/L Na2CO3, and 10 g/L Na2SiO3 at 60°C (Trisnanto et al,2018;Hao et al, 2016;Li et al, 2017) was used for alkali cleaning process. The steel substrate was then removed after 15 minutes in the solution and rinsed with distilled water.…”

“…The substrate modification followed the method published in the literature (Trisnanto et al, 2018). The layer by layer deposition started with the electrodeposition of Cu on the steel substrate on step 1, CuO formation by immersion into H2O2 solution and Stearic Acid Modification as shown in Figure 1.…”

“…The dynamics contact angle measurement was performed following the method published in the literature (Trisnanto et al, 2018). This measurement was used to obtain the sliding angle and contact angle hysteresis information.…”

“…Wang et al (2015) reported of developing a corrosion resistance by spraying highly amphiphobic polymer materials coating surface. Other techniques in developing superhydrophobic surface such as sol-gel, chemical vapor deposition, spraying, spinning, etching, and plasma treatment also have been reported in the literature (Trisnanto et al, 2018;Brassard et al, 2015;Zhang et al, 2014;Gurav et al, 2015;Vilaro et al, 2016;Linda et al, 2012;Cho et al, 2016). Among all these techniques of fabrication, electro-deposition is widely used because it allows full control of the metal deposition to the surface (Shi et al, 2005).…”
