In an era where the concept of green development is deeply rooted,magnesium(Mg)alloy as a light metal has a long-term development prospect in the process of energy saving,emission reduction and environmental improvement.However,anti-corrosion performance of Mg alloy is poor due to the high chemical activity and low equilibrium potential,which limits the development of Mg alloy products.Herein,three-dimensional mesopore hollow polypyrrole spheres(MHPS)were prepared,and the MHPS was inserted into the middle of the stacked hexagon boron nitride(h-BN)lamellae,which allowed the h-BN to be separated forming a further composite with abundant pore structure.Subsequently,the MHPS/h-BN-OH composite was uniformly sprayed on the Mg alloy surface via simple spraying method to form the superhydrophobic surface(SHS).Finally,the slippery liquid infused porous surface(SLIPS)was success-fully fabricated by applying drops of silicone lubricant on the superhydrophobic coating surface.After a series of characterization and testing,the results showed that the stacking of h-BN lamellae was signifi-cantly reduced after h-BN was successfully embedded by MHPS.In addition,the fabricated SLIPS have ex-cellent self-cleaning,mechanical stability,anti-icing and anti-corrosion properties.Therefore,the method of embedding polymer microspheres not only offers a new strategy for h-BN exfoliation,but also the successful prepared SLIPS largely retards the corrosion of Mg alloy while providing new ideas for the development of SLIPS.
