Vibrational sum frequency generation spectra and schematic of surface ordering and packing of ODMS-MIM(+) headgroups and tails at the organic/aqueous interface as function of increasing ionic strength (NaCl concentration). Tunability over the interface was demonstrated by manipulating H-bonding networks and charge screening through variation of the anions in the aqueous phase.
Scientific Achievement
Hydrogen bonding and electrostatic interactions in the aqueous phase control the resulting conformations of the polymers in the organic phase.
Significance and Impact
Learning the design rules for assembly of bio-inspired polymeric membranes will enable new classes of functional interfaces.
