Abstract
Abstract High‐performance elastomers are expected to possess excellent healing and recycling ability, damage resistance in conjunction with high strength and toughness. Herein, a dual dynamic crosslinking strategy is implemented by multiple hydrogen and disulfide bonds to obtain a novel amorphous and transparent polyurethane/nanocellulose elastomer with excellent self‐healing, self‐reinforcing and toughening performance. First, hydrogen bonds are introduced in TEMPO‐oxidized cellulose nanofibers (TCNF) by modification with 2‐ureido‐4[1H]‐pyrimidone (UTCNF), while disulfide bonds (SS) are introduced in the polyurethane (PU) main chain, leading to the formation of dual dynamic cross‐linking networks. The…
