“…For example, Sun and co-workers fabricated LbL films with both healability and high electrical conductivity. 328 Transparent healable conductive films were prepared by deposition of Ag nanowire layers on top of healable bPEIPAAHA, branched poly(ethylenimine) (bPEI) and poly(acrylic acid)hyaluronic acid (PAA-HA) blend LbL films. The resulting films had conductivities much higher than those of ITO on glass.…”

Materials fabrication with nanoscale structural precision based on bottom-up-type self-assembly has become more important in various current disciplines in chemistry including materials chemistry, organic chemistry, physical chemistry, analytical chemistry, biochemistry, colloid and surface chemistry, and supramolecular chemistry. Although the design of new materials based on nanoscale self-assembly is anticipated as a key concept, preparing complete three-dimensional structures at nanoscale precision remains a difficult target using current technologies. Rather, dimension-reduced approaches such as layering of two-dimensional nanostructures into precisely controlled lamellar nanomaterials are currently achievable. In particular, layer-by-layer (LbL) assembly is known as a highly versatile method for fabrication of controlled layered structures from various kinds of component materials using very simple, inexpensive, and rapid procedures. Therefore, fabrication of multilayer films through the LbL deposition process has attracted growing interest from various research communities. The high versatility and flexibility of LbL assembly is continuously creating new concepts, new materials, new procedures, and new applications. In this highlight review, we focus on nanoarchitectonics by LbL assembly. After an initial introduction on the invention and a brief history of the LbL assembly technique, innovations and the evolution of the technique are described based mainly on recent examples, which are categorized into two sections: (i) developments in methodology (technical, material, and phenomenological aspects with expansion of concept) and (ii) progress in applications (physical, chemical/biochemical, and biomedical applications).

Intrinsic self-healing polyborosiloxane (PBS) and its multi-walled carbon nanotube (MWCNT)-reinforced nanocomposites were synthesized from hydroxyl terminated poly(dimethylsiloxane) (PDMS) and boric acid at room temperature. The formation of Si-O-B moiety in PBS was confirmed by Fourier transform infrared spectroscopy. PBS and its MWCNT-reinforced nanocomposites were found possessing water or methanol activated mechanically adaptive behaviors; the compressive modulus decreased substantially when exposed to water or methanol vapor and recovered their high value after the stimulus was removed. The compressive modulus was reduced by 76%, 86%, 90% and 83% for neat PBS and its nanocomposites containing 3.0 wt.%, 6.2 wt.% and 13.3 wt.% MWCNTs, respectively, in water vapor, and the modulus reduction activated by methanol vapor was greater than by water vapor. MWCNTs at higher contents acted as a continuous electrical channel in PBS offering electrical conductivity, which was up to 1.21 S/cm for the nanocomposite containing 13.3 wt.% MWCNTs. The MWCNT-reinforced PBS nanocomposites also showed excellent mechanically and electrically self-healing properties, moldability and adhesion to PDMS elastomer substrate. These properties enabled a straightforward fabrication of self-repairing MWCNT/PBS electronic circuits on PDMS elastomer substrates.

“…These insulating self-healing polymers can be directly utilized as encapsulating materials, dielectric layers, and/or supporting substrates for various electronic devices. [50,71] For examples, a widely used self-healing polymer in energy storage devices was reported by Leibler in 2008. [34] The self-healing polymer, cross-linked by fatty dimer acids and urea based on supramolecular hydrogen bonds, behaved like conventional thermoresponsive rubber and showed recoverable extensibility up to several hundred percent and little creep under load.…”

“…Sun and coworkers demonstrated a self-healing conductor by depositing silver nanowires (AgNWs) on top of an intrinsically healable polyelectrolyte multilayer (PEM) film. [71] The healable film was fabricated by layer-bylayer (LbL) assembly of branched poly(ethylenimine) (bPEI) and poly(acrylic acid)-hyaluronic acid (PAA-HA) blend. When damaged, PEM would swell in the presence of water and cause the fracture surfaces to heal by reforming the ionic bonds.…”

Because of the great breakthroughs of self‐healing materials in the past decade, endowing devices with self‐healing ability has emerged as a particularly promising route to effectively enhance the device durability and functionality. This article summarizes recent advances in self‐healing materials developed for energy harvesting and storage devices (e.g., nanogenerators, solar cells, supercapacitors, and lithium‐ion batteries) over the past decade. This review first introduces the main self‐healing mechanisms among different materials including insulators, electrical conductors, semiconductors, and ionic conductors. Then, the basic concepts, fabrication techniques, and healing performances of the newly developed self‐healing energy harvesting (nanogenerators and solar cells) and storage (supercapacitors and lithium‐ion batteries) devices are described in detail. Finally, the existing challenges and promising solutions of self‐healing materials and devices are discussed.
