Schematic showing how different anions affect the nanostructures of charged, amphiphilic ODMS-MIM(+) oligomers at an air-aqueous interface
Scientific Achievement
Surface pressure–area isotherms suggest anions affect the stability of charged, amphiphilic oligomers at the air-aqueous interface, irrespective of their surface activities.
Significance and Impact
Electrolytes can be used to alter the hydration shell of charged, amphiphilic oligomers at the air-aqueous interface of Langmuir films, thereby providing a means to control the formation of emergent nanostructures.
Research Details
- The effects of different salts (NaF, NaCl, NaSCN) on the nano-structure assembly of charged, amphiphilic oligomers were probed using vibrational sum frequency generation (SFG) spectroscopy and Langmuir trough techniques.
- Experimental data were supported by atomistic molecular dynamics simulations.
