Soft materials are materials that can be easily deformed by thermal stresses or thermal fluctuations at about room temperature. Soft materials include liquids, polymers, foams, gels, colloids, granular materials, as well as most soft biological materials.
Soft pressure sensors drift under prolonged high stress because of the creep of soft materials, which causes inaccurate measurements. Now, through molecular-level design, a leakage-free and creep-free polyelectrolyte elastomer is synthesized, and an iontronic sensor using the polyelectrolyte elastomer shows very low signal drift under a high static pressure.
Pentagonal polyhedral oligomeric silsesquioxane (POSS)-based giant atoms self-assemble into Frank–Kasper phases that have not been previously observed in soft-matter systems.
Schematic illustrations of the alignment behavior induced by SWaP. Photopolymerization was conducted with a scanned UV slit light. Uniaxial molecular alignment was induced when the polymer concentration in the exposure area was high, while it was random when the polymer concentration was low.
Authors introduce triple treatments to advance flexible single-walled carbon nanotube films, achieving a power factor of 20.29 µW cm−1 K−2. High structural stability and flexibility enable the fabrication of a high-power-density flexible device.
Organic cations are typically unstable under low-humidity, alkaline conditions. Here, the authors report an organic cation featuring a proton protected within a cage that can withstand vapor-phase alkaline conditions.
High-density device arrays can be integrated on flexible substrates using a dip-transfer coating method that suppresses adhesive layers from forming between closely spaced devices and uses magnetically self-assembled particles to increase the anisotropic conductivity.
Interest in protein-based fibers is driven by their unique properties, including biocompatibility and biodegradability. This Review summarizes the synthesis and properties of biomimetic protein fibers, such as keratin, collagen, elastin and silk fibers, and their application in energy, air and water treatment, and biomedical uses.

Boroxines, resulting from the reversible dehydration of boronic acids, have been incorporated as structural units into functional materials and molecular assemblies, but their applicability is restricted to non-aqueous environments owing to their inherent water instability. Now, a boroxine structure spontaneously formed from the 2-hydroxyphenylboronic acid dimer enables water-compatible dynamic B–O covalent bonds, expanding their future applicability.
Ageing is a non-linear, irreversible process that defines many properties of glassy materials. Now, it is shown that the so-called material-time formalism can describe ageing in terms of equilibrium-like properties.
