The chelating monomer GMIDA not only has the structure of "semi EDTA" which has strong chelating effect on metal ions

but also can introduce functional chelating groups to the surface of materials through double bond covalently. This kind of functional polymer greatly expands the application range of the material themselves. In this review

firstly

the properties and synthesis methods of GMIDA polymers are briefly introduced

and then the applications of GMIDA polymers in various fields are analyzed. For example

based on the special binding of metal ions to proteins

GMIDA chelating polymers are used in the separation and purification of proteins

the specific recognition of glycopeptides

and the sustained-release of protein therapeutic drugs. The antibacterial effect of p(GMIDA) chelating metal ions is better than that of its anionic polymers

in this reason

GMIDA chelating polymers are used in the field of antibacterial materials. Based on the reversible adsorption and desorption behavior between metal ions and chelating polymers

GMIDA chelating polymers are used in many other fields

such as active packaging materials

sewage treatment

lithium-ion batteries

catalytic chemistry

etc. In addition

GMIDA metal chelating polymers are also widely used in crystal form control

trace metal detection

functional coatings and material modification. In the end

the future development of metal chelating polymers is briefly reviewed and prospected.
