摘要 Learning from nature takes ideas from natural species and develops novel functional materials based on these concepts, e.g., bio-inorganic materials (biomineralization), bio-inspired multiscale structured materials (chiral morphologies), bio-nanomaterials (bio-nanoparticles), hybrid organic/inorganic implant materials (bonelike composites), and smart biomaterials. Many of these smart materials have surfaces that dynamically alter their physicochemical properties in response to changes in their environmental conditions and to triggered control of interfacial properties. In our research, by mimicking the well-ordered multiscale structures of natural interfaces or surfaces, many inorganic nanomaterials with bio-inspired structures and functions have been designed. For example, to develop effective anti-fogging nanomaterials that can provide protection for such surfaces, even when exposed in extreme environments, we designed fly-eye inspired superhydrophobic anti-fogging nanomaterials that have a low adherence force to water droplets and thus resist fogging-induced ice build-up. The development of the fish-scale bio-inspired inorganic nanostructures, which have similar multiscale structures and multiple-functions to that of the natural targets, greatly extends the applications of bio-inspired materials to fields from micromechanical devices to heavy-duty machines as protective coatings against mechanical damage and chemical corrosion, as optical elements in optical devices and photovoltaic energies, and as low-drag or low-friction surfaces in gaseous, liquid, and solid media, etc. Therefore, we believe that the design of bio-inspired nanostructures could provide a new approach for develop novel multifunctional nanomaterials in the future.
