In situ Imaging of Single Polyelectrolyte Chains with the Atomic Force Microscope

CHIMIA, 2019
: This article discusses the possibilities offered by modern atomic force microscopes (AFMs) with ultra-small cantilevers to perform in situ imaging of single adsorbed polyelectrolytes in aqueous solutions.

Asymmetric polyethersulfone membranes modified with polyelectrolyte complexes: Morphology, thermal analysis and transport properties

eXPRESS Polymer Letters
Mixing additives into a polymeric membrane constitutes an easy way to change their properties. Polyelectrolyte complexes (PECs) (polyelectrolytes combined via electrostatic interaction) are good materials for this due to their hydrophilicity, tunable ...

Stochastic coarse-grained simulations of polyelectrolytes [PDF]

, 2020
Stochastic coarse-grained simulations are implemented to investigate the behavior of both strong and weak polyelectrolytes in acqueous solution. A primitive electrolyte model is used to represent polyeletrolytes and mobile ions, whereas the solvent ...

Polyelectrolytes as adhesion modifiers

, 2003
Adsorbed layers of polyelectrolytes have been studied with atomic force microscopy (AFM) and the interferometric surface force apparatus (SFA). Particular emphasis was put on determining the effect of the polyelectrolyte charge density on surface ...

Polyelectrolytes and Their Biological Interactions [PDF]

, 1964
Polyelectrolytes are water-soluble electrically charged polymers. Their properties are determined by the interplay of the electrical forces, the Brownian motion of the macromolecular chain, and intermolecular Van der Waals forces.

Novel polyelectrolytes [PDF]

, 1978
Cationic polyelectrolytes are formed by the polymerization in absence of oxygen of a monomer of the general formula: ##STR1## where x is 3 or more than 6 and Z is I, Br or Cl to form high charge density linear polymers. Segments of the linear polymer may

Ion binding to polyelectrolytes

, 2006
Binding of simple ions to polyelectrolytes is reviewed. Proton binding in excess salt is understood quite well. At intermediate distances between the groups, the binding isotherms broaden due to electrostatic interactions, and are captured by a simple ...

CONDITIONING PROCESS AND CHARACTERIZATION OF FRESH ACTIVATED SLUDGE [PDF]

Journal of Engineering Science and Technology, 2015
Fresh activated sludge in many wastewater treatment plants may be considered unhealthy due to the large amount of organic and organism content. Due to the lack of research on municipal sludge, there is an apparent scarcity of actual data. Thus, this work
