The influence of the chain degree of ionization on the adsorption of weak polyelectrolytes on neutral and on oppositely and likely charged surfaces is investigated, by means of Monte Carlo simulations with a mesoscopic interaction model known as dissipative particle dynamics. The electrostatic interactions are calculated using the three-dimensional Ewald sum method, with an appropriate modification for confined systems. Effective wall forces confine the linear polyelectrolytes, and electric…

Interfacial adsorption of pH-responsive polymers and nanoparticles.

By grafting polyelectrolytes, the interfacial behavior of the nanoparticles can be tuned by changing the pH and salinity of the solution, which is dictated by the contact angle, the pair correlation function between the particles and the oil, the desorption energy, and the particle morphology at the interface.

Coarse-grained simulations of the salt dependence of the radius of gyration of polyelectrolytes as models for biomolecules in aqueous solution

The salt dependent radius of gyration of a polyelectrolyte in aqueous solution is calculated and the scaling exponent of the gyration radius as a function of the polymerization degree is obtained, and it is found that the polyelectralyte retains a stretched conformation during the condensation and re-expansion process.

On the potential of mean force of a sterically stabilized dispersion

The potential of mean force (PMF) is the total free energy of a many-body colloidal system, and consequently it includes all the interactions the colloids experience due to collisions with themselves

Controlling the stability of Pickering emulsions by pH-responsive nanoparticles.

Electrostatic dissipative particle dynamics simulations were conducted to model the interactions between emulsion droplets stabilized by pH-sensitive polyelectrolyte-grafted nanoparticles and discovered that the resistance is attributed to direct electrostatic repulsion, the image charge effect near the water-oil interface, and steric hindrance among extended polymers.

Mesoscopic modeling of structural and thermodynamic properties of fluids confined by rough surfaces.

The interfacial and structural properties of fluids confined by surfaces of different geometries are studied at the mesoscopic scale using dissipative particle dynamics simulations in the grand canonical ensemble and it is found that a structural order-disorder phase transition occurs as the degree of surface roughness increases.

It is demonstrated that image forces can considerably reduce the degree of polyElectrolyte adsorption and, as a major consequence, inhibit the charge inversion of the substrate by the polyelectrolytes.

Solvation force induced by short range, exact dissipative particle dynamics effective surfaces on a simple fluid and on polymer brushes.

It is shown that despite the short range of all forces in the model, the solvation force can be finite at relatively large distances and therefore does not depend only on the range of the interparticle or solvent-surface forces.
