Polyelectrolyte - an overview | ScienceDirect Topics

Polyelectrolyte membranes are synthesized on surface of the charged supports via sequential coating of anionic and cationic polyelectrolytes. This assembly technique named as layer by layer (LbL) is attractive for the preparation of NF and RO membranes, and the obtained dense structure can limit passage of ions through the membranes [28].

Aug 10, 2016 · Charge on particle-dispersant interface (e.g., slipping plane) is a complicated and less understood phenomenon. Usually, almost all of the naturally occurring surfaces and molecules exhibit negative charge (e.g., cell membrane, proteins, lipids, mucus etc.). On the contrary cationic surfaces and molecules are often synthetic.
