Abstract
New self-healing hydrogels based on the strong host-guest interaction of carborane (CB) and β-cylcodextrin (CD) were constructed through CB-grafted dextran and β-CD-grafted poly(acrylic acid). The storage modulus of the hydrogels could reach as high as 10 kPa, and the hydrogels exhibited an outstanding self-healing rate in minutes.
