Charging of weak polyelectrolytes
Michal Borkovec, Ger J. M. Koper Email. [email protected], [email protected] September 15, 2013 Direct link www.colloid.ch/polyelectrolytes In aqueous solutions, bases bind protons, while acids dissociate them. For weak acids and bases, these protonation reactions occur in the intermediate pH range. Dealing with monoprotic or diprotic acids and bases, the corresponding binding isoth...
متن کاملCharge Regulation of Interacting Weak Polyelectrolytes
We introduce a generalized nonuniform mean-field formalism to describe the dissociation of weak rodlike polyelectrolytes (PEs). Our approach allows for two-sublattice symmetry breaking which in titration curves is associated with a plateau for intermediate dissociation degrees. We first test our method in the case of a single weak PE by comparison with exact enumeration studies and show that it...
متن کاملNanoparticle modification by weak polyelectrolytes for pH-sensitive pickering emulsions.
The affinity of weak polyelectrolyte coated oxide particles to the oil-water interface can be controlled by the degree of dissociation and the thickness of the weak polyelectrolyte layer. Thereby the oil in water (o/w) emulsification ability of the particles can be enabled. We selected the weak polyacid poly(methacrylic acid sodium salt) and the weak polybase poly(allylamine hydrochloride) for ...
متن کاملControlling the physicochemical properties of weak polyelectrolyte multilayer films through acid/base equilibria*
Multilayer thin films prepared from weak polyelectrolytes can exhibit a rich suite of anomalous physicochemical properties. One of the major factors that influence the properties of such films is the acid/base chemistry of the weak functional groups of the polyelectrolytes. In fact, the apparent dissociation constants of weak polyelectrolytes can shift by as much as 1–4 pH units upon incorporat...
متن کاملIon distribution in multilayers of weak polyelectrolytes: A neutron reflectometry study.
Neutron reflectometry was used to determine the distribution of salt ions and water in thin poly(acrylic acid) and poly(allylamine hydrochloride) polyelectrolyte multilayers assembled with and without salt. Increasing salt concentration reverses the exclusion of water from the substrate region, eventually leading to an asymmetric segregation of water near the substrate at high salt concentratio...
