The interaction of hybrid nanoparticles inserted within surfactant bilayers

Doru Constantin

Résumé

We determine by small-angle x-ray scattering the structure factor of hydrophobic particles inserted within lamellar surfactant phases for various particle concentrations. The data are then analyzed by numerically solving the Ornstein–Zernicke equation, taking into account both the intra- and interlayer interactions. We find that particles within the same layer repel each other and that the interaction potential (taken as independent of the concentration) has a contact value of 2.2kBT and a range of about 10 Å. If the amplitude is allowed to decrease with increasing concentration, the contact value in the dilute limit is about 5kBT for a similar range
