The invention discloses an intelligent dressing capable of controlling wound pH value. The intelligent dressing comprises a base layer and an acting layer contacted with wounds; the base layer is prepared from calcium alginate hydrogel; and the acting layer is prepared from a hydrogel prepared via cross-linking polymerization of gamma-polyglutamic acid and epsilon-polylysine. The intelligent dressing is capable of controlling wound pH value; calcium alginate hydrogel is taken as the base layer, so that a problem that the mechanical strength of the acting layer is extremely low is solved; contact of the acting layer with wounds is capable of maintaining a low oxygen humid sealed environment effectively, realizing intelligent adjustment of pH value of wound fluid to be about 5.5, and accelerating healing speed of wounds. The intelligent dressing capable of controlling wound pH value is a flaky hydrogel dressing material, application range is wide, and application prospect in the field of wound dressing is promising.
