成果简介：Marine bifouling has been plaguing people for thousands of years. While various strategies have been developed to antifouling (including superoleophobic) coatings, none of these exhibits self-healing property because the bestowal of a zoetic self-repairing function to lifeless artificial water/solid interfacial materials is usually confronted with tremendous challenges. Here we present the first self-repairing underwater superoleophobic and anti-biofouling coating through the self-assembly of hydrophilic polymeric chain modified hierarchical microgel spheres. The obtained surface material not only has excellent underwater superoleophobicity but also owns very good subaqueous anti-biofouling property. More importantly, the oil- and biofouling- resistant properties of this new class of surface material can be repetitional regeneration in water once its surface is mechanically damaged, similar to the skins of some marine organisms such as sharks or whales. This approach is feasible and easily mass-produced, and could open a new pathway and possibility for the fabrication of other self-healing functional water/solid interfacial materials.
