first-principles study of electron mobility in cationic cost
electron mobilities in two similar conjugated polyelectrolytes (cpes) with an identical conjugated backbone but different counterions and appended charges are calculated from first-principles. an excellent agreement with experimental mobility is found for the cationic cpe. the relative importance and respective role of cpe structural components including backbone, appended groups, water treatment

a survey on cationic polyelectrolytes and their applications
cationic polyelectrolytes are water-soluble polymers bearing positive ionic groups along the backbone or in side chains. these cationic polymers are synthesized by free radical polymerization of acrylamide and their derivatives by the copolymerization method, which includes solution, precipitation, and emulsion techniques. the mannich reaction is another important method by which the cationic
application of polyelectrolytes for contaminant removal low cost,1. introduction. polyelectrolytes are a type of water-soluble polymer with a multitude of ionizable groups. the combination of their polymeric characteristics and ionizable behaviour give polyelectrolytes various useful properties, and thus they offer a broad spectrum of applications in a wide variety of fields, including but not limited to pharmaceuticals, biomedicine, medicine, petroleum
