This study utilized choline chloride (ChCl) as the hydrogen bond acceptor, while acrylamide (AM) and urea functioned as hydrogen bond donors. A P(AM-Urea) composite hydrogel was successfully synthesized using a ternary deep eutectic solvent (DES) system and in-situ polymerization. The effects of varying AM/Urea molar ratios on the swelling behavior, mechanical properties, self-healing abilities, and pressure sensitivity of the hydrogels were systematically analyzed. The results indicated that an increase in AM content significantly enhanced both the swelling capacity and mechanical strength of...
