“…During the evaporation process of the droplet, since the evaporation rate of the edge is greater than that of the center, the solution flows radially outward, and the capillary force brings the suspended particles in the solution from the center to the edge and finally accumulates to form a coffee ring.

The wettability and adhesion of biological surfaces often depend on their periodically arranged hybrid micro–nano array structures. Various fabrication processes are designed to mimic biomimetic micro–nano array surfaces. This review summarizes the types of micro–nano array structures and analyzes fabrication methods based on top‐down and bottom‐up construction, including templating, etching, self‐assembly, and electrospinning/electrospraying. This review focuses on the shape reconfiguration of surface micro–nano array structures under physical stimuli, as well as the changes in material surface properties during the reconfiguration process. In addition, the applications of biomimetic micro–nano array composite surfaces in the fields of droplet transport, adhesion properties, sensors, and soft robotics are also discussed, and the current challenges and prospects in this field are identified.

Biodegradable conductive films are crucial for the sustainable development of wearable electronics. In this work, a flexible and degradable conductive film was prepared based on a carefully designed interface of polylactic acid (PLA) electrospun fibers and silver nanowires (AgNWs). The amphiphilic triblock copolymer was added to PLA solution for electrospinning, followed by solvent posttreatment to induce the hydrophilic block of the amphiphilic triblock copolymer to migrate to the fiber surface. Dopamine can be uniformly polymerized on the surface of hydrophilic PLA fibers, and the prepared PLA@PDA fiber film can form a good interface combination with AgNWs. The electrical conductivity of AgNWs/PLA@PDA flexible film can reach 258.5 S cm−1, showing obvious Joule heating effect and good mechanical properties. Degradation experiments showed that in phosphate buffered saline, the PLA molecular chain showed a dynamic equilibrium due to the scission and rearrangement of the ester groups and degraded slowly, while AgNWs/PLA@PDA degraded rapidly under alkaline conditions. Our study provides a simple and controllable method to prepare flexible degradable electronic films, which is expected to be applied to flexible wearable bioelectrodes.

“…Making full use of the block characteristics of polar and nonpolar segments of the poly(styrene-(ethylene- co -butylene)-styrene) (SEBS) molecular chain, , the adhesion and cohesion of coating are effectively tuned and optimized with the aid of the long-chain acrylate. Meanwhile, the polyaniline (PANI)-decorated carbon nanotube (CNT) serves as an effective microwave absorber, which also presents a positive influence on the adhesion and cohesion of the coating due to the bonding interaction. , The resultant peelable MA coating yields a competitive effective absorption bandwidth (EAB) of 8.8 GHz and exhibits excellent peelable ability with controllable yet reversible adhesion release on various substrates, complex surfaces, and application scenarios. Especially, the EAB shows 93% retention even for ten coating-peeling cycles and more than 98% retention even after 8 h of accelerated corrosion.…”

The peelable microwave absorption (MA) coating with reversible adhesion for stable presence on substrates and easy release without any residuals is highly desired in temporary electromagnetic protection, which can quickly enter and disengage the electromagnetic protection state according to the real-time changeable harsh surroundings. On the contrary, with the incorporation of abundant absorbent to achieve excellent MA ability, the tunable adhesion and sufficient cohesion are extremely challenging to fulfill the above requirement. The reported peelable coatings still have problems in controlling adhesion/cohesion strength and coating release, facing substantial residuals after peeling even using complex chemical modification or abundant additives. Herein, a peelable MA coating based on the block characteristics of polar and nonpolar segments of poly(styrene-(ethylene-co-butylene)-styrene) (SEBS) is successfully developed. The polyaniline-decorated carbon nanotube as a microwave absorber plays a positive influence on the adhesion/cohesion of the coating due to bonding interaction. The competitive effective absorption bandwidth (EAB) of 8.8 GHz and controllable yet reversible adhesion release on various substrates and complex surfaces have been achieved. The reusability endows peelable MA coating with 93% retention of EAB even after ten coating-peeling cycles. The coating with excellent chemical and adhesion stability can effectively protect substrates from salt/acid/alkali corrosion, showing over 98% retention of EAB even after 8 h of accelerated corrosion. Our peelable MA coating via a general yet reliable approach provides a prospect for temporary electromagnetic protection.
