Unimodal Nano-Sized Bentonite-E Modified by Organic Monomeric/Polymeric Methacrylic Acid Zwitterions

Resumo

The reaction of methacrylic acid and aminoguanidine (AG) synthesized monomeric water-soluble biocidal zwitterions ZiMAAG that were used for organic modification of unimodal nano-sized bentonite-E (75-80% montmorillonite) with low metal carbonate contents. A hybrid nanostructure bentonite-E/ZiMAAG was produced by radical polymerization in situ of ZiMAAG with ammonium persulfate [(NH₄)₂S₂O₈] as initiator. The new nanocomposite was studied by elemental analysis and thermal and physicochemical properties.
