Berberine-loaded montmorillonite composite material as well as preparation method and application thereof

The invention relates to the technical field of montmorillonite modification, and particularly discloses a berberine-loaded montmorillonite composite material as well as a preparation method and application thereof. According to the invention, the montmorillonite is subjected to surface activation treatment so as to obtain montmorillonite with uniform performance and a certain microporous structure; na < + > and NH4 < + > are passively embedded into the montmorillonite by adopting an electrode pressurization form, so that the interlayer distance of the montmorillonite is greatly increased; after washing, dehydration treatment is performed to remove attached water and free water, so that later water absorption is facilitated; by constructing a supramolecular network, the loading capacity of berberine is further improved; the preparation method comprises the following steps: dipping a montmorillonite matrix into a berberine solution to embed berberine into montmorillonite, so as to obtain the berberine-loaded m
