Nature Communications, Published online: 10 June 2026; doi:10.1038/s41467-026-73807-5 Soft materials often fail through snap-through instability, but overcoming this instability requires a polymer network that is soft at small strains and stiffens early at larger strains. Here, the authors design an ordered nanoplastic–elastomer network that shows earlier stiffening while retaining small-strain softness.
