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.

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.

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.

Natural rubber exhibits the strain-induced crystallization (SIC). By using WAXD, the orientation of NR crystal formed by SIC under planar elongation was revisited. We found that the orientational state of the crystal lattice possesses a continuous margin of the orientation angle between 6.4 and 19.6° for the ac plane with respect to the surface of the specimen sheet in the real NR specimen. This orientational state could be accomplished as a result of balancing the preferential parallel orientation of (120) planes (the slip planes) and C = C planes with respect to the surface of the specimen sheet.

Helical protein assemblies are an important biological structure, but are challenging to mimic with synthetic materials. Here, the authors report the use of peptoids to form nanohelix structures with controllable supramolecular chirality.

An article in Nature Communications describes a straightforward strategy to synthesize chemically recyclable polytrithiocarbonates with diverse structures.

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.
