| 摘要 | Polyurethane nano-coatings were prepared by adding nano-concentrates with nanometer zinc oxide (nano-ZnO) to polyurethane coating. The dispersion state of nanoparticles was observed by TEM images. SEM observation and FT-IR analysis indicate that the nano-coating with 1% ZnO nanoparticles can retain better morphological structure than the nano-coating with 5% ZnO nanoparticles after 500 h accelerated aging. It is known from XPS analysis that the anti-oxidation properties of polyurethane coating are enhanced by 1% ZnO nanoparticles through the nano-network and destroyed by 5% ZnO nanoparticles due to the strong light catalysis. A small change in capacitances of nano-coatings with 1% ZnO nanoparticles before and after accelerated aging indicates that 1% ZnO nanoparticles improve the corrosion resistance of coating, while a large increase in capacitances of nano-coating with 5% ZnO nanoparticles before and after accelerated aging demonstrates that 5% ZnO nanoparticles damage the corrosion resistance of coating. |
