Hydrogels Based On Alkylated Chitosan And Polyelectrolyte Copolymers
(2018)
Hydrogels formed by alkylated chitosan with N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride and synthetic copolymers forming polyelectrolyte complexes are presented. The copolymer polyelectrolytes were synthesized ...
Counterion condensation on polyelectrolyte chains adsorbed on charged surfaces
(Elsevier Science, 2015-09-20)
We developed a Monte Carlo systematic study into the effect of counterion condensation on the polyelectrolyte adsorption process on charged surfaces. Polyelectrolyte is modeled as a full-flexible chain whose size is ...
Microphase separation and aggregate self-assembly in brushes of oppositely charged polyelectrolytes triggered by ion pairing
(American Institute of Physics, 2020-10)
This work applies a molecular theory to study the formation of lateral self-assembled aggregates in mixed brushes composed of polyanion and polycation chains. In order to overcome the well-known limitations of mean-field ...
Adsorption of poly(mono-n-alkylmaleate-alt-N-vinyl-2-pyrrolidone) sodium salts at air/water interface
(2006)
The surface properties of poly(mono-n-alkylmaleate-alt-N-vinyl-2- pyrrolidone) sodium salts derivatives with n=8, 10, 12, 16, and 18 carbon atoms in the side chain were analyzed. The surface tension behavior suggests that ...
Critical adsorption of polyelectrolytes onto charged Janus nanospheres
(Royal Soc Chemistry, 2014-01-01)
Based on extensive Monte Carlo simulations and analytical considerations we study the electrostatically driven adsorption of flexible polyelectrolyte chains onto charged Janus nanospheres. These net-neutral colloids are ...
Ion‐Exchange equilibria in cationic polyelectrolytes
(1994)
A method which allows the evaluation of phenomenological ion exchange constants Kex is proposed and tested in a cationic polyelectrolyte system. Results for nitrate/chloride exchange are nearly constant over the entire ...
Counterion association to cationic polyelectrolytes in methanol/water mixtures
(1995)
The effect of the nature of the medium on the chloride and bromide condensation to a cationic polyelectrolyte was studied. Methanol/water mixtures were used as solvent in order to vary continuously the properties of the ...
Voltage-Triggered Structural Switching of Polyelectrolyte-Modified Nanochannels
(American Chemical Society, 2020-03)
Synthetic solid-state nanochannels modified with polyelectrolyte brushes are an important class of stimuli-responsive nanofluidic devices. This work theoretically addresses the design of a voltage-triggered nanomechanical ...
Rheological Properties of Citrus Pectin Dispersions and Its Blends with Polyquaternium-7 and Colloidal Particles
(Wiley-blackwellHobokenEUA, 2014)
Surfactant presence in a multilayer polyelectrolyte-enzyme system improves its catalytic response
(Elsevier Science Inc, 2009-05)
Self-assembling of poly(allylamine) containing an osmium polypyridil complex (PAOs) alternatively with sodium dodecyl sulfate (SDS) and glucose oxidase (GOx) generates a ternary multilayer system, (PAOs/SDS/PAOs/GOx)n. The ...
