Covalent Attachment of Quaternary Ammonium Group to Geopolymer Surface With Silane Coupling Agent to Enable Simultaneous Adsorption of Cations and Anions

open access: yesAdvanced Materials Interfaces, EarlyView.
Modification of geopolymer surface with a silane coupling agent containing quaternary ammonium group enables the development of dual‐functioning ion exchanger for both cations and anions. In the present study, the performance of this material was demonstrated for the uptake of ammonium and nitrate from water.

Redox‐Confined Interfacial Polymerization Enables Mechanically Robust and Self‐Adhesive Nanofilms

open access: yesAdvanced Materials Interfaces, EarlyView.
Redox‐confined polymerization of a simple thiol monomer at a water‐organic interface generates robust freestanding films with nanoscale thickness. The resulting disulfide‐crosslinked nanofilms combine high stiffness with intrinsic adhesion to soft substrates, enabling conformal contact with artificial skin without additional functionalization.
