Intelligent materials are emerging composite materials that have boomed since the 1990s. In the 21st century, the variety of intelligent materials is continuously expanding and the domains of which are constantly being broadened. The intelligent material system is of great scientific significance - it combines studies that explore nature, mimic nature and surpass nature, which involve a multitude of structures and functions. It also provides novel ideas, new theories, and cutting-edge methodologies for the innovation of science and technology. Thus, mimicking the microstructures and functions found in nature will build a bridge between biology and technology, which may provide inspirations for solving today's technological problems. Inspired by nature, the authors proposed a concept of Binary cooperative complementary micro/nanoscale interfacial materials. Based on this design concept, the contact and coupling of heterogeneous materials will result in novel properties on the surface or interface of materials, which may create new functional materials and devices. This book gives a complementary introduction about biomimic intelligent micro/nanoscale interfacial materials, devoting largely to the intelligent materials with special wettabilities.
