Mechanically robust self-repairing polyurea elastomers: The roles of hard segment content and ordered/disordered hydrogen-bonding arrays

[Display omitted] •A series of room temperature self-repairing polyurea elastomers (PUs) based on hydrogen bond with improved strength and toughness is reported.•A model was proposed to explain the effect of hard segment content and temperature on order-disordered hydrogen-bonding arrays, and how th...
