Mechanical Properties and Structures of Clay-Polyelectrolyte Blend Hydrogels
Gels, 2018 Our recent studies have shown that the hydrogels prepared by blending clay, a dispersant of clay, and a polyelectrolyte (sodium polyacrylate (PAAS)) possess excellent mechanical properties.

Effects of APP/SiO2 polyelectrolyte composites on wood-plastic composite [PDF]
MATEC Web of Conferences, 2019 This paper was aimed to evaluate process of APP/SiO2, which used Nano-crystalline cellulose (NCC) modified ammonium polyphosphate (APP) as anionic polyelectrolyte (a-APP), and cationic polyethyleneimine (PEI) modified Nano–SiO2 as cationic ...

Conformation of a Polyelectrolyte Complexed to a Like-Charged Colloid
, 2001 We report results from a molecular dynamics (MD) simulation on the conformations of a long flexible polyelectrolyte complexed to a charged sphere, \textit{both negatively charged}, in the presence of neutralizing counterions in the strong Coulomb ...

Shifts in Redox Formal Potentials Accompanying the Incorporation of Cationic Complexes in Perfluoro Polycarboxylate and Polysulfonate Coatings on Graphite Electrodes [PDF]
, 1984 The formal potentials of several redox couples incorporated in coatings of a perfluoropolycarboxylate on graphite electrodes were measured and compared with the formal potentials of the same couples in homogeneous solution.

Swelling Properties of Hydrogels Containing Phenylboronic Acids
Chemosensors, 2013 Phenylboronic acids are a class of compounds that bind glucose and other sugars. When polymerized into hydrogels, they provide a convenient nonenzymatic means for sensing glucose concentration, provided competing sugars are present at negligible ...

Electrostatic analysis of the charged surface in a solution via the finite element method: The Poisson-Boltzmann theory [PDF]
AUT Journal of Electrical Engineering, 2016 Electrostatic potential as well as the local volume charge density are computed for a macromolecule by solving the Poisson-Boltzmann equation (PBE) using the finite element method (FEM). As a verification, our numerical results for a one dimensional PBE,

Journal de Physique, 1988 The adsorption of uncharged polymers is, due to numerous efforts over past decades, fairly well understood. Some insight exists into the structure of the adsorbed layer, and the effect of the important parameters molecular weight, solvency and polymer/surface interaction has been investigated. Theory and experiment are beginning to converge.
