The present invention relates to a PMAA and PAA based hydrogel having an ordered lamellar structure, consisting of an aryl monomer having a PI stacking effect and a carboxyl monomer having hydrogen bonding action. The hydrogel of the invention through hydrogen bonds and Pi Pi accumulation release drug control system of double switch, realizes continuous regulation of drug release; gel swelling performance test showed that the hydrogel of the invention has excellent pH responsiveness; drug release system simulating human metabolism experiments showed that the hydrogel the preparation of controlled release the system can realize the release and metabolism of human body system of drug metabolism, effectively reduces drug waste and side effect on the human body by excessive drug.
