Preparation method and application of CdS/TiO2 core-shell structure nanocomposite

The invention discloses a preparation method and application of a CdS/TiO2 core-shell structure nano composite material, a coating prepared by the method can improve the photogenerated cathode protection performance of the coating, the metal anti-corrosion effect is effectively improved, and due to the fact that CdS is wrapped by the unique structure, cadmium ions are effectively inhibited from being separated out through CdS photocorrosion, and the corrosion resistance of the nano composite material is improved. Compared with a conventional TiO2/CdS core-shell structure nano composite material, the nano composite material is more environment-friendly and more excellent in corrosion resistance under the combined action of the nano composite material and the epoxy resin. 本发明公开了一种CdS/TiO2核-壳结构纳米复合材料的制备方法及应用，采用本发明方法制备的涂层能够改善涂层光生阴极保护的性能，有效提升金属防腐效果，且由于其独特的结构裹附CdS有效抑制了CdS光腐蚀析出镉离子，在和环氧树脂的共同作用下，比常规的TiO2/CdS核-壳结构纳米复合材料更环保，防腐性能更加优异。
