Abstract

The use of geo-nano TiO2/SiO2 self-cleaning material as a coating prototype for deck line pipe to stop corrosion on tanker ships was successfully studied in this study. The objective was to produce a synthetic material that would be able to clean itself and be applied to tanker ship deck line pipes. The self-cleaning materials were created by changing the amount of Nano TiO2/SiO2 added in three distinct compositions of a geopolymer composite based on metakaolin. Applying the geopolymer paste to the surface of stainless-steel pipes was part of the composition testing procedure. The sample was prepared for testing after the proper composition was determined. By calculating the sample's contact angle, the self-cleaning qualities were examined; the average result was 57.3. These findings suggest that the sample has self-cleaning qualities even though it is still hydrophilic, allowing liquids to moisten its surface. Field Emission Scanning Electron Microscopes—Energy Dispersive Spectroscopy (FESEM-EDS) and XRD were used to characterize the materials’ microstructure and test for crystallinity. Tests were done on the samples both before and after they were submerged in seawater. A homogenous connection between the geopolymer paste and the nanoTiO2 and nanoSiO2 aggregates was demonstrated by the favorable results of the FESEM study. Following immersion in seawater, the sample's surface morphology showed evidence of peeling as a result of seawater damage. A new Cl peak was found in the XRD and EDS diffractogram analysis, which suggested that seawater (NaCl) and geopolymer were reacting. Furthermore, the soaked sample's EDS test revealed that the composite surface did not produce the corrosive FeCl2 crystal phase. This indicates that the production of corrosion material (FeCl2) on the surface of stainless steel may be inhibited by Nano TiO2, a photocatalytic anti-corrosion material.
