Introduction: bio-inspired surface textures-nature's tool for delivering functional surfaces 'It is not the strongest of the species that survives, nor the most intelligent, but the most responsive to change,' said Charles Darwin. Survival of the fittest is a famous phrase of Herbert Spencer, which describes the idea that, in nature, there is a competition to survive and reproduce. Survival and change are two critical terms, especially as species on earth over millions of years are in continuous combat with changing environments. These environments are typically harsh for organisms to live in, but despite these difficulties organisms have survived and thrived by building harmonic ecosystems within divergent environments including marshy and muddy; deep cold and snowy; hot, dry and desert; and more. Living organisms interact and interface with their surroundings through their outer layers, their surfaces which have adapted and evolved with novel but simple designs and functional properties in this process of combat and survival.The surface (and sub-surface) of an organism, also called skin, is an important interface between an organism and its environment, serving a mission critical role in the process of adaptation and survival. Skin surfaces interact with aggressive environmental factors such as temperature, moisture, abrasive agents such as sand and ice, pH, bacteria and viruses, light, mating abrasive or super smooth surfaces, etc. and their combinations. To combat these aggressive factors, skins have evolved unique design architectures that achieve multifunctional properties including (but not limited to) adhesion, hydrophobicity, hydrophilicity, thermal-management, anti-reflection, structural colors, and spherical vision as highlighted in Fig. 1.The skins of organisms, from here onwards called surfaces, deliver these environment-specific properties by combining textures and material chemistries to exploit classical laws of physics to achieve superior functional properties. The term surface texture captures various facets of a construct including the repetitive arrangement of features, the various shapes and sizes of features (in 2-D and 3-D), and the hierarchical distribution of quasi-periodic connected structures in a multi-dimensional space CIRP Annals -Manufacturing Technology xxx (2018) xxx-xxx

“…Bio-inspired micro-structured surfaces have an apparent drag reduction effect in turbulent flowing conditions [25][26][27][28][29], and have extensively been put into application in fluid engineering [30,31].

Article Highlights• Micro-dimple imprinting method is explored and adopted • Relationship between plastic deformation capacity and curing degree is investigated • Instantaneous micro-imprinting method is exploited • Forming precision of instantaneous micro-imprinting can surpass 90% Abstract Nano/micro-imprinting technology based on polymer material coating has attracted increased attention throughout the world in the past several decades, and it is at present progressively developing into a hot topic, in which how to improve the manufacturing efficiency is becoming the urgent issue to be resolved. Polymer's curing process is exactly complicated and sophisticated, which involves simultaneously performing physical and chemical changes, when the curing reaction reaches certain level, the system will abruptly transform into insoluble, non-melting gel with rapidly increased viscosity and rigidity, which can generate fixed deformation under persistent external pressure. In this paper, the plastic deformation capacity of epoxy resin in the curing process is investigated by the micro-dimple imprinting experiment, and the relationship between forming precision and curing degree is ascertained adopting the DSC (differential scanning calorimetry) method. In addition, the instantaneous micro-imprinting technology based on the micro-grooves is explored, and the experimental results indicate that the forming precision can surpass 90%. The paper will establish a novel avenue for application of the nano/micro imprinting technology into practical engineering.Entering the 21 st century, with the increasingly serious energy crisis and climate warming, saving energy and reducing emission of greenhouse gases has turned into an important issue, in which lowering the friction force on the contact surfaces between moving objects can take a critical role. For protecting surfaces from corrosion and obtaining the smoothness, polymer coatings have been widely exploited in Correspondence: Y. Luo,

“…Among them, the morphology and size parameters of the microstructures for drag reduction are the key factors that influence the drag reduction ability. Various riblet morphologies, such as single-layer and double-layer riblets, have been fabricated through copied biological templates [17,[26][27][28][29][30], metal element arrays [10,31], machined aluminum [9], machined acrylic [13,14], paint [12], photolithography [16,32], soft lithography [28], nanoimprint lithography [18], profile grinding [33,34], rolling [30,35], laser etching [14,19,32,36,37], chemical etching [38], and 3D printing [3,39] technologies. However, multilayer hierarchical microstructures are arrays of three-dimensional multilayer hierarchical microstructures with characteristic dimensions ranging from the micrometer to the submillimeter scale.…”

Drag reduction is a significant challenge for many industries, such as ships, pipelines, aircraft, energy, and transportation. Multilayer hierarchical microstructures can inhibit the development of vortices near the wall, which is beneficial to drag reduction. However, existing methods have difficulty performing the controlled fabrication of complex multilayer hierarchical microstructure arrays. Here, a novel triple lithography method based on three-layer hybrid masks is proposed for the controlled fabrication of three-dimensional multilayer hierarchical microstructure surfaces. The capability of the proposed process is verified by the multilayer hierarchical microstructures. In the fabrication process, a special lithography sequence is designed based on the hybrid mask materials. The drag reduction ability of the multilayer hierarchical microstructures is investigated in a closed air channel measurement system. The experimental results demonstrate that the fabricated multilayer hierarchical microstructures exhibit significant drag reduction ability under certain conditions. Conceptual models based on the fluid-solid coupling interface interaction are proposed to explain the drag reduction mechanism of multilayer hierarchical microstructures. The proposed fabrication method provides a powerful means for practical engineering applications of various bioinspired functional surfaces, such as drag reduction, anti-icing, antifouling, self-cleaning, and superhydrophobic surfaces.
