Abstract A self-healing CB[7]/PAA hydrogel was prepared with acrylic acid (AA), H2O, cucurbituril[7] (CB[7]), potassium persulfate (KPS) and NaCl as raw materials. The self-healing process of CB [7]/PAA hydrogel was investigated by means of FT-IR and 1H NMR techniques. Results show that the hydrogel networks formed during the self-healing of CB [7]/PAA hydrogel are mainly induced by the existence of multiple hydrogen bonds, and after the self-healing, the maximum tensile elongation of CB[7]/PAA hydrogel can reach about 1.73 times of that of the as prepared ones. Within a range of low AA content, the swelling and swelling rate of the hydrogel increase with the increasing AA content, while in a range of high AA content, the swelling and the swelling rate decreases with the increasing AA content; the swelling and swelling rate of the hydrogel in the aqueous solution of pH=7.6 were obviously higher than those in the aqueous solution of pH=10.0 and pH=4.0. The kinetic index n, rate constant K and water diffusion coefficient D of CB[7]/PAA hydrogel were acquired corresponding to non-Fickian diffusion mode. It follows that the swelling of CB [7]/PAA hydrogel is in accordance with the non-Fickian diffusion mode, and the diffusion rate of water molecules is comparable to that of the relaxation rate of chain segments in the hydrogel.
