<p>Method for reversibly switchable cross-linking of specified monomers comprises cross-linking the monomers by adding complexable metal ions so as to form a polymer and bond-breaking the polymer by applying a direct voltage and changing a pH value of the polymer and changing the temperature of the polymer. Method for reversibly switchable cross-linking of monomers comprises: (a) cross-linking the monomers by adding complexable metal ions so as to form a polymer; (b) bond-breaking the polymer by applying a direct voltage and changing a pH value of the polymer and changing the temperature of the polymer. The monomers include compounds of formula (I) and (II).
