Abstract: The invention relates to a preparation method of an intelligent gel material and in particular relates to a preparation method of thermosensitive ion imprinting gel. The method comprises the following steps: using chloromethyl styrene and amine compounds such as ethylenediamine to react to generate a ligand, then using the ligand and a specific metal perchlorate to react to obtain a complex which can chelate specific metal ions, using the complex, N-isopropylacrylamide, N,N'-methylenebisacrylamide, polyoxyethylene (10) stearate and azodiisobutyronitrile to perform a copolymerization reaction under a certain condition, and performing purification, separation and other processes to finally obtain the thermosensitive ion imprinting gel product which can chelate the specific metal ions. The thermosensitive ion imprinting gel material prepared by the method has the characteristics of thermosensitivity, ion recognition and strong identification response capability to metal ions, namely Cu<2+>, Ni<2+>, Co<2+>, Pt<2+>, Pd<2+>, Zn<2+>, Cd<2+> and Au<3+>.
