Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Area of Science:

  • Colloid and Surface Chemistry
  • Materials Science
  • Physical Chemistry

Background:

  • Cetyltrimethylammonium bromide (CTAB) is a common surfactant forming micelles in aqueous solutions.
  • The morphology of CTAB micelles can be influenced by additives like alcohols.
  • Understanding micellar transitions is crucial for developing novel materials and applications.

Purpose of the Study:

  • To investigate the micellar transitions in CTAB-water solutions induced by 1-octanol (C8OH).
  • To characterize the phase behavior, rheological properties, and micellar structures.
  • To validate experimental findings with computational simulations.

Main Methods:

  • Construction of the ternary phase diagram for CTAB-C8OH-water.
  • Rheological measurements including oscillatory-shear frequency sweeps and viscosity.
  • Small-angle neutron scattering (SANS) for micellar parameter determination.
  • Molecular dynamics (MD) simulations for molecular interactions and aggregation.

Main Results:

  • A phase diagram revealed varied solution behaviors with increasing C8OH concentration.
  • Rheology showed a transition from viscous/viscoelastic fluids to elastic gels.
  • SANS provided insights into micellar aggregation numbers and shapes.
  • MD simulations elucidated molecular interactions and aggregation dynamics.

Conclusions:

  • 1-octanol induces higher-order micellar transitions in CTAB solutions, from ellipsoidal to rodlike to wormlike.
  • The observed transitions correlate with changes in rheological properties and micellar morphology.
  • Computational simulations complement experimental data, offering a deeper understanding of the system.
