Interfacial energy, structure and adhesion of polymers are significant in the science and technology of films, elastomers, fibers, coatings, and adhesives. Furthermore, such fundamental knowledge is practically important in fabricating advanced functional devices. Recently engineers pay an increasing attention to biological surfaces trying to understand nature solves environmental problems and use these solutions to obtain materials and surfaces with special functionalities. Nature, through billions of years of trial and error, has produced effective solutions to numerous complex real-world problems. The rigorous competition of natural selection shows biological materials are developed according to a genetic algorithm and can adjust to environmental conditions. Many biological surfaces with special functions, such as the self-cleaning effect on a lotus leaf, a water harvesting capability on a Stenocara beetle’s back, the high adhesion and friction force provided by a gecko’s foot, the anisotropic dewetting behavior on a rice leaf, the non-reflective property on a moth eye, are all related to the unique micro- and nanostructures on the surfaces. Our objective is to provide a greater understanding of various properties associated with biological materials and transfer this knowledge to fabricate the practical applications of polymers.
