Construction and Properties of Zn LDH-NFA Superhydrophobic Oleophylic Films
Zn LDH-NFA films were prepared by coating Zn zif-l films on stainless steel mesh with zinc acetate dihydrate and 2-methylimidazole as the precursor.The contact angle measurement showed that the film did not reach the superhydrophobic state at this time,and finally it was soaked in a stearic acid solution with low surface energy.For knowing the hydrophobicity of the film more comprehensively,X-ray diffraction(XRD)was used to characterize the structure of the film layer.Through the contact Angle test,the contact Angle of water droplets on the film reached 151.7°.The separation efficiency of oil and water mixture was 96％.Anti-fouling and anti-water tests show that the film has a high degree of self-cleaning ability and super hydrophobic performance.The results show that the film has good structural stability and corrosion resistance after soaking in strong acid and alkali solution.
