Imparting Ultrahigh Strength to Polymers via a New Concept Strategy of Construction of up to Duodecuple Hydrogen Bonding among Macromolecular Chains

Interconnecting macromolecules via multiple hydrogen bonds (H‐bonds) can simultaneously strengthen and toughen polymers, but material synthesis becomes extremely difficult with increasing number of H‐bonding donors and acceptors; therefore, most reports are limited to triple and quadruple H‐bonds. Herein, this bottleneck is overcome by adopting a quartet‐wise approach of constructing H‐bonds instead of the traditional pairwise method. Thus, large multiple hydrogen bonds can be easily established, and the supramolecular interactions are further reinforced. Especially, when such multiple H‐bond motifs are embedded in polymers, four macromolecular chains—rather than two as usual—are tied, distributing the applied stress over a larger volume and more significantly improving the overall mechanical properties. Proof‐of‐concept studies indicate that the proposed intermolecular multiple H‐bonds (up to duodecuple) are readily introduced in polyurethane. A record‐high tensile strength (105.2 MPa) is achieved alongside outstanding toughness (352.1 MJ m−3), fracture energy (480.7 kJ m−2), and fatigue threshold (2978.4 J m−2). Meantime, the polyurethane has acquired excellent self‐healability and recyclability. This strategy is also applicable to nonpolar polymers, such as polydimethylsiloxane, whose strength (15.3 MPa) and toughness (50.3 MJ m−3) are among the highest reported to date for silicones. This new technique has good expandability and can be used to develop even more and stronger polymers.

Suppressing the water activity is challenging to achieve high‐performing aqueous zinc ion batteries (AZIBs), especially for its practical climate adaptability. Reconstructing the H‐bond network and repealing the solvation water can effectively reinforce the covalency inside water molecular. Here, a hydrogel electrolyte formula utilizing ClO4− anions and hydrophilic ─NH2 on polyacrylamide chains is shown to bond with water molecules, while the zincophilic glucose preferentially regulate Zn2+ solvation. The multifunctional hydrogel structure can effectively disrupt the intrinsic H‐bond network and inhibit the interface side‐reactions induced by active water. Finally, the delayed freezing point and expanded voltage stability window are realized, which promotes the ZIBs steady operate in a wide temperature range. When operating at 70 and −30 ˚C, the Zn//NVO battery achieves high specific capacity of 488 and 254 mAh g−1, respectively, surpassing most of the previously reported results. Remarkably, the pouch battery delivers the state‐of‐the‐art specific capacity of 438.1 mAh g−1 and realizes a capacity retention of 76.3% after 400 cycles at 200 mA g−1.
