The superhydrophobic oleophilic surface exhibits hydrophobicity towards aqueous media which can achieve self-cleaning and drag reduction effects. Moreover it exhibits oleophilicity towards oil media. In view of the different contact angles of superhydrophobic and oleophilic surfaces with oil and water oil-water separation can be achieved and the utilization rate of oil can be improved. Objective This study aims to achieve hydrophobic or even superhydrophobic properties while maintaining oleophilicity to oil droplets on micro-nano structured array surfaces and to extend the service life of such surfaces by leveraging their recovery capability after damage. Methods A preparation method for a micro-nano structured array shape memory surface was proposed by using the chemical corrosion method and the mold method and a thermally-induced shape memory polymer surface was prepared. Results Experiments demonstrated that the prepared micro-nano structured shape memory surface exhibited hydrophobicity and lipophilicity. Conclusion The thermallyinduced shape memory polymer surface can achieve superhydrophobicity by adding micro-nano structures. Different micronano structured surfaces show different degrees of hydrophobicity. Moreover the reversible transformation of the destruction and recovery of micro-nano structures can be realized by changing the temperature thus achieving the transformation between hydrophilicity and hydrophobicity. At the same time the micro-nano structured array shape memory surface has good durability. A simulation model of the micro-nano structured array shape memory surface was established for wetting simulation. The contact angles of each surface at various stages of the prepared surface were calculated by combining experiments and simulations. The agreement between simulation and experimental data enhances the credibility of the data.
