Summary: | The invention belongs to the field of macromolecular self-assembly materials and environmental ionic pollutant detection and particularly relates to a macromolecular electrostatic self-assembly sensing material for ion detection as well as a preparation method and an application of the material. The sensing material is a multi-layer film formed by micro hydrogel particles with an ionic chelation function and surface negative charges and cationic polyelectrolyte through self-assembly under the action of electrostatic force, and selective detection of heavy metal ions in water is realized with a quartz crystal microbalance technique.
