Abstract
The cover by Johannes Berg shows the schematic representation of calcium alginate consisting of mannuronic acid (green) and guluronic acid (red), cross-linked by calcium cations (yellow). An interpenetrating additional polymer is polyethyleneimine (blue), thereby constituting a composite hydrogel. Positively charged methylene blue is selectively adsorbed in the alginate hydrogel due to its negatively charged polymer backbone. Along with that, negatively charged congo red is selectively adsorbed by the positively charged polyethyleneimine. (DOI: 10.1002/pol.20230215)
期刊介绍：
Part A: Polymer Chemistry is devoted to studies in fundamental organic polymer chemistry and physical organic chemistry. This includes all related topics (such as organic, bioorganic, bioinorganic and biological chemistry of monomers, polymers, oligomers and model compounds, inorganic and organometallic chemistry for catalysts, mechanistic studies, supramolecular chemistry aspects relevant to polymer...
