Room-temperature self-healing and self-growing of the exoskeleton with aligned structures in insects has few analogs in synthetic materials. Insect cuticle, such as elytra in beetles, with a typical lightweight lamellar structure, has shown this capability, which is attributed to the accumulation of phenol oxidase with polyphenol and amine-rich compounds in the hard cuticle. In this study, laminar-structure-based intelligence is imitated by incorporating adaptable and growable pyrogallol (PG)-borax dynamiccovalent bonds into a poly(acrylamide)-clay network. The events that lead to crack formation and water accumulation quickly trigger the deprotection of PG. Subsequently, atmospheric O 2 , as a regeneration source, activates PG oxidative self-polymerization. Multiple permanent and dynamic cross-links, with the involvement of the sacrificed borax, and initiation of a series of intelligent responses occur. The fabricated composites with an aligned lamellar structure exhibit outstanding characteristics, such as air/water-triggered superstrong adhesion, self-repairing, self-sealing and resealing, and reprocessing. Moreover, the strategy endows the composites with a self-growing capability, which leads to a 4-to 10-fold increase in its strength in an outdoor climate (up to 51 MPa). This study could lead to advances in the development of air/water-responsive composite materials for applications such as adaptive barriers.

“…In these cases, polyphenol–amine copolymerized networks would be a more suitable priming structure than pure polyphenols/MPNs for secondary functionalization. [ 51,127,274 ] For example, Lee group has very recently developed a polymeric superglue by copolymerization of a polyphenol (PG) and an amine‐containing polymer (PEI). [ 127 ] The observed superglue performances are majorly ascribed to the formation of phenol–amine crosslink networks, as well as adhesiveness from residual phenolic groups.…”

Nature-inspired phenolic chemistries have substantially nourished the engineering of advanced materials for widespread applications in energy, catalysis, and biomedicine, among others. To achieve predictable yet adaptable material structures and properties, the spatial and/or temporal control over the phenolic chemistries per se is increasingly demanded. In this review, a systematic overview of recent strategical advances in the spatiotemporal control of phenolic chemistries in materials science is given. The chemical diversity and reactivity of catechols and polyphenols are first introduced as phenolic building blocks. With a main focus on catechols (especially dopamine), renewed insights into their mechanisms of polymerization/assembly, adhesion, and cohesion are provided. The conditions for tuning phenolic polymerization/assembly are also outlined. This paper focuses on the latest strategies for imparting controlled manipulation of phenolic chemistries in terms of many aspects: growth kinetics, chemical compositions and structures, dimensions and architectures, spatial patterns, and surface functionality. Finally, critical issues facing this field with perspectives delivered on future research are discussed. As envisaged, this review will provide helpful guidance to orchestrate state-of-the-art phenolic chemistries and materials science for producing materials with intended, application-oriented properties and functions.
