Organisms in nature have evolved a variety of surfaces with different tribological properties to adapt to the environment. By studying, understanding, and summarizing the friction and lubrication regulation phenomena of typical surfaces in nature, researchers have proposed various biomimetic friction regulation theories and methods to guide the development of new lubrication materials and lubrication systems. The design strategies for biomimetic friction/lubrication materials and systems mainly include the chemistry, surface structure, and mechanics. With the deepening understanding of the mechanism of biomimetic lubrication and the increasing application requirements, the design strategy of multi-strategy coupling has gradually become the center of attention for researchers. This paper focuses on the interfacial chemistry, surface structure, and surface mechanics of a single regulatory strategy and multi-strategy coupling approach. Based on the common biological friction regulation mechanism in nature, this paper reviews the research progress on biomimetic friction/lubrication materials in recent years, discusses and analyzes the single and coupled design strategies as well as their advantages and disadvantages, and describes the design concepts, working mechanisms, application prospects, and current problems of such materials. Finally, the development direction of biomimetic friction lubrication materials is prospected.

This review explores the present knowledge of the unique properties of shark skin and possible applications of its functionalities, including drag reduction and swimming efficiency. Tooth-like denticles, with varied morphologies, sizes, and densities across the shark’s body, significantly influence the flow and interaction of fluids. Examining dermal denticle morphology, this study unveils the functional properties of real shark skin, including mechanical properties such as stiffness, stress-strain characteristics and the denticle density’s impact on tensile properties. The adaptive capabilities of the Mako shark scales, especially in high-speed swimming, are explored, emphasizing their passive flow-actuated dynamic micro-roughness. This research contains an overview of various studies on real shark skin, categorizing them into skin properties, morphology, and hydrodynamics. The paper extends exploration into industrial applications, de tailing fabrication techniques and potential uses in vessels, aircraft, and water pipesfor friction reduction. Three manufacturing approaches, bio-replicated forming, direct fabrication and indirect manufacturing, are examined, with 3D printing and photocon figuration technology emerging as promising alternatives. Investigations into mechani cal properties of shark skin fabrics reveal the impact of denticle size on tensile strength, stress and strain. Beyond drag reduction, the study highlights the shark skin’s role in enhancing thrust and lift during locomotion. The paper identifies future research directions, emphasizing live shark testing and developing a synthetic skin with the help of 3D printing incorporating the bristling effect.

Bioinspired and biomimetic materials have revolutionized many aspects in the engineering sciences, ranging from basic technologies to advanced applications such as the Gecko's nanostructure for sticky tapes or the sharkskin for swimming suits. Research in these subjects in Germany has been supported by several national priority research programs since 2009 (SPP 1420: Biomimetic Materials Research: Functionality by Hierarchical Structuring of Materials, [1] SPP 1569: Generation of Multifunctional Inorganic Materials by Molecular Bionics, 2012-2019 [2] ), which strongly accelerated developments and investigations in the field. Recently, also photonic applications of bioinspired strategies have come within reach, demonstrating the huge potential of the approach nature has chosen in many directions (SPP 1839: Tailored Disorder -A science-and engineering-based approach to materials design for advanced photonic applications, 2015-2024 [3] ). These developments have been accompanied by a biennial DGM Bioinspired Materials conference series, which was launched in 2012. [4] The present Advanced Functional Materials feature issue now proudly presents accompanying papers from the 6 th DGM "Bioinspired Materials [5] " together with additional most recent and advanced research work pushing the limits of our exciting interdisciplinary research field. The collected perspectives, reviews and research articles represent the current state-of-the-art in the design of functional and structural materials and systems inspired by principles found in living nature. Main topics of this include the study and formation of hierarchical structures and the properties of complex-shaped biological materials. The transfer of biological principles into functional materials and systems made of organic and/or inorganic components represents a further main area. Beside synthesis and
