Polyacrylate‐based electrically conductive adhesives (PA‐based ECAs) have attracted much attention due to their wide applications in precise instruments and consumer electronics. To obtain high‐performance and environmentally friendly PA‐based ECAs, their main properties and corresponding mechanisms to performance, chemical constitutions and structure–function relationships should be well understood, and the applications of recent PA‐based ECAs should be comprehensively summarized. This review focuses on the progress of PA‐based ECAs in the past two decades and discusses the featured properties, preparation of PA, the selection of conductive fillers and the adhibition of the ECAs. The aim of the review is to find the challenges of high‐performance ECAs and offer some measures and foresee their future development. Highlights: Preparation methods of polyacrylate (PA)‐based composites are presented.Properties of PA‐based electrically conductive adhesives (ECAs) are outlined.Selection of conductive fillers and the adhibition of ECAs are discussed.Representative applications of PA‐based ECAs are exhibited.Present main challenges and future solutions are highlighted.

Special porous anodic aluminum oxide (AAO) membranes are created on Al in a phosphonic acid electrolyte solution through one‐step anodic oxidation and modified with polydimethysiloxane using a vapor deposition technique. In this context, the anodic oxidation time is tuned during its process. As such, the Al surface's wettability, and self‐cleaning property are controlled by the tunable anodic oxidation time, for the anodic oxidation, time can regulate the structure of the AAO and the proportion of the air‐liquid interface.

Superhydrophobic surfaces are widely found in nature, inspiring the development of excellent antiwater surfaces with barrier coatings isolating the underlying materials from the external environment. Here, the naturally occurring superhydrophobicity of lotus seedpod surfaces is reported. Protective coatings that mimic the lotus seedpod are fabricated on AZ91D Mg alloy surfaces with the synergistic effect of robust superhydrophobicity and durable corrosion resistance. The predesigned titanium dioxide films are coated on AZ91D by an in situ hydrothermal synthesis technique. Through sonication assisted electroless plating combined with a self-assembling method, the densely packed Cu-thiolate layers are uniformly plated with robust adhesion on the Mg alloy substrate, which function as a superhydrophobic barrier that can hold back the transport of water and corrosive ions contained such as Cl−. Notably, the two extreme wetting behaviors (superhydrophilicity and superhydrophobicity) as well as corrosion resistance and improved corrosion resistance can be easily controlled by removal of the hydrophobic materials ( n-dodecanethiol) at elevated temperature (350 °C) and modifying them at room temperature for 18 cycles, indicative of exceptional adhesion between the superhydrophobic coating and the underlying AZ91D Mg alloy.

Superhydrophobic Fe(OH)3 surface was obtained on AZ31 (Mg-3Al-1Zn) magnesium alloy via a simple solution immersion process and post-modification in absolute stearic acid through a hydrothermal synthesis technique. The superhydrophobic surface, which had a static water contact angle of 163.7±2.9° and a water roll-off angle of <1°, exhibited long-term durability in air and high chemical stability over a wide pH range (pH 1–13). Tafel polarization and electrochemical impedance spectroscopy measurements demonstrated that the superhydrophobic surface was strongly resistant to corrosion. [ABSTRACT FROM AUTHOR]

The repeatable wettability of the facile-to-fabricate porous copper surface shows superhydrophobicity in air and improved superhydrophobicity under oil. The resultant 3D copper foam can separate and capture oils from water with high separation efficiency, fast capture kinetics, fine mechanical resistance to water impact, and good recyclability.

Inspired by the lotus seedpod, Mingjie Liu, Lei Jiang, and co‐workers report in article number 1605446 how to form exceptionally superhydrophobic and corrosion‐resistant surfaces on AZ91D Mg alloys by using self‐assembled monolayers. The surfaces exhibit a thermally controlled wetting transition between superhydrophilic and superhydrophobic states, and tunable corrosion resistance. This strategy will lead to improved corrosion‐resistant Mg alloys and thermally responsive “surface engineering”. [ABSTRACT FROM AUTHOR]
