Production of superhydrophobic galvanized iron plate via electrodeposition method

This study aimed to developed a superhydrophobic substance and apply it to the surface of a galvanized iron. using electrodeposition,the researchers have produced a superhydrophobic surface in a cathodic surface by electrodepositing it in a galvanized iron plate. the electrodeposition process utilizes an electrolytic solution of manganese chloride (mncl24h2o),myristic acid (ch3(ch2)12cooh) and 95% ethanol for 15 minutes in 30v. using sem (scanning electron microscope) to characterize the superhydrophobic surface,the researchers found out that it was made of cluster of microscale particles which were composed of many smaller nanoparticles which allows the superhydrophobic surface to store a lot of air thus prevents water from entering or contacting the surface. using ftir (fourier transform infrared spectroscopy),the researchers determined that the superhydrophobic surface in the cathodic surface is composed of mn myristate (mn[ch3(ch2)12coo]2). the superhydrophobic surface was attributed to its contact angle measuring at 150º or greater which made the water in contact with it to occupy a minimum area of contact thus this can be easily removed at a tilting or rolling angle of less than 3º. © school of engineering,taylor’s university.
