Abstract Detachable pressure sensitive adhesives (PSAs) show great potential in recycling the bonded components toward a circular economy, yet existing challenges such as strict conditions, and time‐consuming, adhesive residues after detachment significantly hinder developments applications. Here, ionoadhesive (PSIA) tape is first designed that has excellent interfacial toughness to various substrates (≈1.8 kJ m −2 ) can be electrically detached with high efficiency under safe voltages (≥90% within 1 min). The unique properties are achieved by introducing liquid‐free lithium salt into poly(ionic liquids) establish multiple non‐covalent interactions (NCIs) including strong electrostatic interactions, moderate bonds, weak ion‐dipole hydrogen bonding interactions. NCIs not only strengthen physical crosslinking networks improve mechanical performances but promote dissociation of ion transport properties. Additionally, elaborately low T g intrinsic modulus features endow PSIA adhesion reworkability, recyclability, re‐adhesion ability. It believed this work offers new strategy for designing detachable fully recyclable tapes, which facilitates reuse reduces industrial waste.

Abstract Autonomously self‐healing, reversible, and soft adhesive microarchitectures structured electric elements could be important features in stable versatile bioelectronic devices adhere to complex surfaces of the human body (rough, dry, wet, vulnerable). In this study, we propose an autonomous self‐healing multi‐layered patch inspired by octopus, which possess robust adhesion properties dry/underwater conditions. To implement autonomously octopus‐inspired architectures, a dynamic polymer reflow model based on structural material design suggests criteria for three‐dimensional patterning elastomers. addition, microstructures with different moduli endows efficient ability, human‐friendly reversible bio‐adhesion, mechanical deformability. Through programmed molecular behavior microlevel hybrid multiscale bioinspired exhibited against rough skin surface under both dry underwater conditions while enabling restoring performance after damaged (over 95% healing efficiency 24 h at 30°C). Finally, developed skin‐mountable electronics repeated attachment minimal irritation laminating thin gold electrodes octopus‐like structures. Based intimate contact skin, successfully obtained reliable measurements during motion image

Supramolecular Adhesives Inspired by Nature: Concept and Applications

Biomimetics, Год журнала: 2025, Номер 10(2), С. 87 - 87

Опубликована: Фев. 1, 2025

Supramolecular chemistry, a relatively newly grown field, has emerged as useful tool to fabricate novel smart materials with multiple uses. Adhesives find numerous uses, from heavy engineering biomedical science. are available in nature; inspired by them and their mechanism of adhesion, several supramolecular adhesives have been developed. In this review, chemistry for the design fabrication is discussed. The discussion divided into two segments. first one deals key forces, implication designing adhesives. second part, applications discussed suitable examples. This type review casts light on current advancements field along prospects development.

Bioinspired Adhesives with Debonding-on-Demand Capability

ACS Macro Letters, Год журнала: 2025, Номер unknown, С. 420 - 427

Опубликована: Март 18, 2025

Adhesives with debonding-on-demand (DoD) capability can simplify and improve manufacturing processes, extend the life cycle of products, facilitate recycling, thus attracting fast-growing interest for use in different sectors. A general design approach DoD adhesives is based on supramolecular polymers, which be disassembled by an external stimulus, allowing modification physical properties these materials. However, adhesive strength generally limited to a few megapascals, their synthesis often quite involved. Here, we report that problems overcome family were inspired structure function natural resin shellac. These are linear oligomers bisphenol diglycidyl ether secondary diamines have, despite widespread cross-linked epoxy thermosets, remained unexplored far. We show if molecular weight limited, highly soluble melt-processable produced. Adhesion tests performed lap joints made stainless steel substrates reveal shear 3.5-16 MPa, upper limit this range exceeds bond shellac blueprint many previous adhesives. demonstrate debonding upon heating above glass transition temperature readily possible broken easily rebond without any loss strength.
