Herein, we synthesized Ca(OH)2 microcapsules with ion-responsive shells composed of cross-linked poly-ionic liquids (CPILs). By exchanging PF6− with Cl− in water, the hydrophobic poly-ionic liquids (PILs) on the shell are converted to hydrophilic channels. The encapsulated Ca(OH)2 can permeate through the hydrophilic channels and release OH−. Meanwhile, the Cl− content can be reduced. The release rate of Ca(OH)2 is influenced by the content of monomers and concentration of Cl− ions in water… CONTINUE READING
