Key Points

  • The goal is to develop a zwitterionic polymer brush that can efficiently adsorb and desorb rare-earth metal ions.
  • Developed a sulfobetaine-type zwitterionic polymer brush on porous silica particles
  • Utilized surface-initiated atom transfer radical polymerization to create the polymer brush
  • Characterized the synthesized polymer for adsorption-desorption activities
  • Successfully synthesized a zwitterionic polymer brush on silica particles
  • Demonstrated effective adsorption and desorption of rare-earth metal ions
  • Showed potential for environmental applications in removing pollutants

Abstract

This study realized to develop a sulfobetaine-typed zwitterionic polymer brush on a porous silica particle (P-SiO2-poly(DMAPS)) through surface-initiated atom transfer radical polymerization (SI-ATRP), and demonstrate its applicability as an adsorption–desorption...
