Synthetic and natural polyelectrolytes have been the subject of fundamental and applied studies for nearly a century. Due to substantial advances both in experimental methods and theoretical approaches, since the 1990’s polyelectrolyte research has undergone a considerable speed-up. On the one hand, interest in polyelectrolytes is spurred by their fascinating properties, such as water solubility, intra- and interchain interactions, the strength of which can be tuned simply by varying salt concentration, and ionic conductivity. These properties make polyelectrolytes attractive from the application-oriented point of view, such as stabilizer of colloidal suspensions, additives to modify flocculation and viscosity, and superabsorbers. Functional polyelectrolytes combine the useful properties intrinsic to polyelectrolytes with added functionality provided by specific features of the polymer backbone, such as delocalized electrons in conjugated chains. Combined functionality can be used to create materials with highly interesting optical, electro-optical, and electronic properties.
On the other hand, the understanding of polyelectrolytes still belongs to the most challenging and most exciting problems in polymer physics and physical chemistry. Despite much effort and substantial progress during the last two decades, much more work is ahead to achieve a quantitative agreement between theory and experiments for a lot of problems, such as counterion condensation, chain stiffness, and formation of complexes. It is still a major open problem to have a satisfactory model explaining the coupling between small ions in solutions and polyelectrolyte charges, which is necessary to understand how electrostatics affects the behavior of polyelectrolytes.
Many biologically relevant macromolecules, such as nucleic acids, polypeptides, and polysaccharides, are polyelectrolytes. Electrophoresis is a well-established method for the fractionation of polyelectrolytes and more specifically, DNA. Hydration-mediated interactions play an important role in the field of biological polyelectrolytes, but are not well understood on nano-scales.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed Open Access monthly journal published by MDPI.
