The invention relates to a production method and a product of a novel multiwalled carbon nanotube-dopamine-polyethyleneglycol diacrylate hydrogel film. The method concretely comprises the following steps: 1, adding dopamine into a cross-linking agent solution under an anoxic condition, stirring the dopamine and the cross-linking agent solution at 45-55 DEG C in a shady place for 1-3 d, and freeze-drying the obtained solution to obtain a dopamine cross-linking agent; 2, adding a multiwalled carbon nanotube solution to the dopamine cross-linking agent, uniformly mixing the multiwalled carbon nanotube solution and the dopamine cross-linking agent, and adding polyethyleneglycol diacrylate and a photoinitiator to the obtained mixed solution to prepare a precursor solution; and 3, preparing the hydrogel from the precursor solution. The multiwalled carbon nanotube-dopamine-polyethyleneglycol diacrylate hydrogel film produced in the invention self-folds during transition from a dry environment to a water-containing environment, is independent from the concentration of the multiwalled carbon nanotube-dopamine, has the characteristics of self coiling, conductivity, cell adhesion ability and biocompatibility, affects cell differentiation, has a bone- and nerve tissue-like form after self-coiling, and has application potential in the biomedical science field.
