Self-Assembly of Polyion–Surfactant Ion Complex Salts in Mixtures with Water and n-Alcohols
Phase behavior and structural features were investigated for "complex salts", consisting of the cationic hexadecyltrimethylammonium (CTA) surfactant with polyacrylate (PA(n), n = 30 or 6000) counterions, mixed with water and different n-alcohols (ethanol, butanol, hexanol, octanol, and decanol). The liquid crystalline structures formed were identified by small-angle X-ray scattering measurement...
متن کاملComplexation in Polyelectrolyte Solution with Divalent Surfactant
We study a simple model of DNA divalent cationic surfactant complexation. We find that the combination of electrostatic and hydrophobic effects leads to a cooperative phenomenon in which as the amphiphile is added to the solution containing DNA, a large fraction of the DNA’s charge is neutralized by the condensed divalent cationic surfactants, forming the surfoplex. This binding transition occu...
متن کاملSize-controlled polyelectrolyte nanocapsules via layer-by-layer self-assembly
Nanomaterials have found many important applications in biomedical, pharmaceutical, electronic, and molecular diagnostic fields. The recent introduction of electrostatic layer-by-layer (LbL) self-assembly technique enables the design and development of polymer/polymer and polymer/nanoparticle complexes at nanometer scale [1]. The LbL technique is based on alternate adsorption of oppositely char...
متن کاملOnset of self-assembly in polymer-surfactant systems
– The onset of self-assembly in a dilute aqueous solution containing a flexible polymer and surfactant is theoretically studied. Focusing on the effect of the surfactant on polymer conformation and using a conjecture of local instability (partial collapse) of the polymer at the onset of self-assembly, we obtain several simple predictions: (i) polymer–surfactant self-assembly always starts at a ...
متن کاملInterfacial polygonal patterning via surfactant-mediated self-assembly of gold nanoparticles
In this work, we explored the formation processes of interfacial polygonal patterning via surfactant-mediated self-assembly of gold nanoparticles (AuNPs). We found that a balance between DDT-capped AuNPs and PVP-passivated AuNPs is a key to making these inorganic-organic thin films. The interfacial polygonal patterning possesses many processing advantages and flexibilities, such as controllable...
