Direct Observation of Polymer-Binding Site on Calcite Crystal by FE/SEM: Regulation of Binding Abilities by a Rotation of Amide Group in Poly(carboxylate) to CaCO3 Crystals

Poly{1-[(Z)-3-carboxyl-2-propenylaminomethyl]ethylene} binding on the edge of calcite crystals was observed directly by 13C CP/MAS NMR and FE/SEM measurements. Comparing the results taken both before and after the washing process, we were able to make these observation because the polymer ligand weakly bound to the CaCO3 crystals.
