This study shows how poly(dimethyl diallylammonium chloride) (polyDMDAAC) controls surfactant adsorption on silica. A polymer layer enhances sodium dodecyl sulfate (SDS) adsorption and alters SDS/C(12)E(6) mixture behavior.

Area of Science:

  • Surface chemistry
  • Polymer science
  • Colloid science

Background:

  • Surfactant adsorption on surfaces is crucial in many industrial processes.
  • Controlling adsorption behavior of anionic and mixed surfactants is challenging.
  • Hydrophilic silica surfaces interact with various charged species.

Purpose of the Study:

  • To investigate the use of a cationic polyelectrolyte, poly(dimethyl diallylammonium chloride) (polyDMDAAC), for manipulating surfactant adsorption.
  • To examine the effect of polyDMDAAC on the adsorption of sodium dodecyl sulfate (SDS) and SDS/C(12)E(6) mixtures on hydrophilic silica.
  • To explore how different polyDMDAAC deposition conditions influence surfactant adsorption.

Main Methods:

  • Deposition of polyDMDAAC layers onto hydrophilic silica surfaces.

  • Adsorption studies of anionic surfactant SDS and mixed SDS/C(12)E(6) surfactants.
  • Analysis of surfactant adsorption under varying polyDMDAAC concentrations and ionic strength (NaCl).

    • Main Results:

    • PolyDMDAAC deposition promotes SDS adsorption onto silica.
    • A polyDMDAAC layer significantly modifies the adsorption of SDS/C(12)E(6) mixtures, leading to SDS-rich surfaces.
    • Higher polyDMDAAC concentrations and 1 M NaCl result in thicker polymer layers and altered surfactant adsorption reversibility.

    Conclusions:

    • PolyDMDAAC is an effective agent for controlling surfactant adsorption on silica surfaces.
    • The polymer layer's properties, influenced by deposition conditions, dictate surfactant adsorption behavior.
    • This work provides insights into surface modification strategies for tailored adsorption properties.
