“…Due to the fine micro‐/nano structure of the tree frog‐inspired surface, the ball‐flat contact mode is frequently utilised for adhesion testing because of its small contact area and high precision [31, 33–35, 37, 38, 43, 45, 48, 49, 54]. In this mode, the friction and normal adhesion forces can be measured by the lateral movement or normal separation of the spherical probe on the structured surfaces.…”

“…Although these soft materials have an elastic modulus comparable to tree frog toe pads, it remains an intractable challenge to manufacture them at the nanoscale. In addition, tin bronze [52], silver [53], and AISI 4140 steel [54] have also been used to create adhesion surfaces that mimic tree frog toe pads. In general, the choice of materials for the construction of tree frog-inspired adhesive surfaces is primarily based on their processability and is limited to several specific polymers.…”

“…Lubricants are crucial to the operation of slewing bearings. Inspired by the behaviour of tree frog toe pads in regulating body fluids, the hexagonal micropillar arrays were constructed on the bionic slewing bearing surface, enabling the even spreading of lubricants on the surface [54]. We anticipate that the bionic wet surfaces with switchable and anisotropic adhesion properties may show a bright prospect in more extended fields such as smart climbing robots and non-destructive patches.…”

Wet adhesion has widespread applications in the fields of wearable electronics, medical devices and intelligent robots. In nature, many organisms have evolved with unique wet adhesion properties to adapt to complex habitats and climb in wet environments without falling. Tree frogs, as crawling masters in tropical rain forests, are representative of wet adhesion and give novel inspirations to design artificial wet adhesive materials by mimicking their specialised hexagonal structures and/or mucus composition. In this review, we first overview the research progress of tree frog toe pads from the perspective of toe pad structure and adhesion mechanism. Then, wet adhesive materials inspired by tree frog toe pads are systematically summarised from (i) the typical polymers, (ii) the preparation approaches, (iii) the adhesion test methods and (iv) the typical artificial adhesion surfaces. Third, various applications of bioinspired wet adhesive surfaces are highlighted. Finally, we present future challenges and opportunities to develop tree frog‐inspired wet adhesive materials.

Graphene and other 2D materials have been extensively studied as solid lubricants in recent years. Low friction can sometimes be observed in those 2D lubricants, and one possible mechanism is that scroll-shaped nanostructures are formed during friction, which decreases the contact area and energy barrier, thus substantially reducing friction. The integration of graphene with metal or metal oxide nanostructures can further enhance its lubrication properties by increasing film formation ability and easy shearing of the nanosheets. However, it is not possible to reliably promote the formation of such nanoscroll-shaped low friction wear products, which limits the reproducibility and application of such nanostructures as solid lubricants. In this study, we address this issue by creating a scalable method for the synthesis of hybrid graphene-titanium oxide (G–TiO2) nanoscrolls and demonstrating their potential as solid lubricants with macroscopic coefficient of friction as low as 0.02 in ambient conditions. Our approach to generate the nanoscrolls is based on the in situ sol–gel synthesis of TiO2 on graphene followed by spray-freeze-drying–induced shape transformation. The solid lubrication performance of such G–TiO2 nanoscrolls can be further enhanced by applying a thin graphene oxide primer layer, which provides high affinity to both the substrate and the active materials. These hybrid nanoscrolls hold promising potential for applications in aerospace, automotive, and precision manufacturing fields as effective solid lubricants. Graphical Abstract
