Bio-inspired interfacial materials are new class of functional materials. The materials with special wettability have emerged as a powerful tool for solving the real-world issues in both researches and applications relating to physics

chemistry

engineering

etc. Within the last decade

the functional interfaces possessing extreme interaction with different fluids has been massively designed and prepared

such as superhydrophobicity

superhydrophilicity

and so on. On the basis of the unique interaction between fluids and solids

these functional interfacial materials offer great opportunity to develop the fluid delivering process

which could open a new way to optimize the current chemical engineering. In this review article

we firstly introduce the basic knowledge of bio-inspired interface materials and the special wetting phenomena in solid/liquid/gas three-phase systems. In the second part

five important applications in field of chemical engineering were reviewed

including heat transfer

multiphase separation

anti-corrosion of reactors and pipes

heterogeneous catalysis

and the directional transport of fluids. The perspective and the current challenge of “how to apply the bio-inspired interface materials” are proposed in the last part.
