Abstract:In order to investigate the effect of surfactants on the nanocomposite electrodeposition process， the effects of common anionic， cationic and nonionic surfactants on electrodepositing process of WO₃-Cu nanocomposite coatings were studied. The surface morphologies and composition of the WO₃-Cu coating obtained in the electrodepositing with surfactants addition were analyzed by SEM and energy dispersive X-Ray spectroscopy （EDS ）. Contact angle measurement， self-cleaning property test， friction ， wear test and photocatalysis test were taken to value the wetting， self-cleaning properties， wear resistance and photocatalytic properties of the WO₃-Cu coatings， respectively. The results showed that different surfactants had a great influence on the surface morphology and WO₃ contents of WO₃-Cu coatings. In the composite electrodeposition using a combination of cationic and non-ionic surfactants， the content of WO₃ in WO₃-Cu coatings could reach maximum value of 25.9% . After the fluorination modification，the contact angle of the WO₃-Cu coating surfaces was about 155°. Compared to the pure Cu，the composite coatings had significantly self-cleaning properties，wear resistance and photocatalytic properties.
