THE SYNTHESIS AND CHARACTERIZATION OF NANOMATERIAL ZNO-CUO PP AS AN ANTICORROSIVE MATERIAL ON THE SHIP HULL USING AN ELECTROCHEMICAL METHOD

Corrosion on the hull of the ship which is an electrochemical process due to seawater which has very low resistivity. The mechanism of corrosion occurs because of the electrochemical process due to the flow of negative poles to the positive pole. Basically corrosion is the event of the release of electrons from metals (iron or steel) that are in an electrolyte solution such as sea water. Whereas positively charged atoms of metal (Fe+3) will react with hydroxyl (OH-) ions to form rust (ferric hydroxide [Fe(OH)3]). Similar studies in modifying Zn to have anti-corrosive properties have been carried out such as modifying Mn, Fe, Sn, and Ni metals. In this study modified Zn composite materials using Polypropylene waste material and CuO material. Polypropylene is an organic material, low conductivity, and cannot be ionized, ZnO as anti-corrosion particles, CuO as fouling, and PP as a matrix. The initial findings show that it can be made material that has a strong, durable, and environmentally friendly anti-corrosion properties
