“…28 We also noticed that the pulvinus had a sucker-like structure with a protuberant closed circle in the middle (Figure 2f 1 ). This structure favors pinning of the liquid because of the close contact with the water 29 in conjunction with the radially distributed rough-textured geometry on its surrounding areas (Figures 2f 2 and f 3 ).…”

Generally, highly efficient liquid transfer is difficult to achieve in open fibrous systems, as compared with traditional closed systems, because capillary coalescence frequently occurs when fiber arrays interact with a liquid. Dandelion pappi, which are flexible fiber arrays with open radial geometries, exhibit the unique ability to capture and hold large amounts of water steadily. Drawing inspirations from this natural system, we developed an artificial flexible glass fiber array with a radial geometry that is capable of holding large volumes of liquid and controllably transferring the liquid onto a substrate. The highly efficient liquid transfer of the open fibrous array can be attributed to the synergistic effects of the flexibility of fibers that radially arranged with a big open angle that enables a distinct elastic deformation of the fibers and the consequent formation of a large space within the fiber array for liquid storage, and the highly adhesive property of fibers that helps the pining of three-phase contact line on the fibers. This unique open system may provide a novel strategy for highly efficient and controllable liquid transfer.

“…As-prepared films are not only superhydrophobic but also highly adhesive. [89] Another example are vertically aligned (VA) single wall carbon nanotube (SWNT) arrays produced via a combination of PECVD and fast heating process which have the highest macroscopic adhesive force among all synthetic and natural gecko feet. Furthermore, dry adhesives based on these vertically aligned SWNT exhibit reversible semiconducting behavior under load as well as excellent thermal resistance due to the unique thermal and electric properties intrinsic to SWNT.…”

In this review a strategy for the design of bioinspired, smart, multiscale interfacial (BSMI) materials is presented and put into context with recent progress in the field of BSMI materials spanning natural to artificial to reversibly stimuli‐sensitive interfaces. BSMI materials that respond to single/dual/multiple external stimuli, e.g., light, pH, electrical fields, and so on, can switch reversibly between two entirely opposite properties. This article utilizes hydrophobicity and hydrophilicity as an example to demonstrate the feasibility of the design strategy, which may also be extended to other properties, for example, conductor/insulator, p‐type/n‐type semiconductor, or ferromagnetism/anti‐ferromagnetism, for the design of other BSMI materials in the future.

Surface tension and contact angle play important roles in capillary dynamics during washing commission of spray-dried detergent powder where interaction between surface chemistry and liquid is concerned. An experimental study for the dynamics of water/ethanol mixtures in both hydrophilic and hydrophobic capillary tubes has been investigated. The combination of water/ethanol mixtures and Trimethylchlorosilane coating on capillaries provides a variety of liquid surface tension and contact angle for the penetrating system. Significant differences of penetrating speed on hydrophilic and hydrophobic tubes indicate that dynamic contact angle dominates hydrophobic surface while liquid surface tension plays a more important role on hydrophilic surface. The speed gradient of different liquids on hydrophilic surface is greater than hydrophobic surface, mainly due to the domination between hydrogen bonding 2 structures and water polarity while liquid moves on surfaces covered with different chemistry, physically absorbed water on silica capillaries or silanol groups covered capillaries.
