文摘

pH-responsive superabsorbent polymers has been successfully synthesized. They showed a desired pH-responsive swelling behavior (up to 70 times their weight). No degree of hydrolysis is observed after swelling in alkaline solutions. Only a limited compressive strength reduction of mortar is observed. Using ‘smart’ pH-responsive SAPs could be promising for self-healing concrete.
