Polyelectrolytes: Science and Application

摘要: Polyelectrolytes, which are a macromolecule dissolved in water or polar solvent, have gained wide attention among scientists and engineers for their application areas. Their different properties allowed them to be used many areas such as soap, body lotions, electrochromic devices, solid-state reference electrode systems, fuel cell exchange membranes, treatment, waste paper production, corrosion protection, cells, electrodialysis, contact lenses, membrane-based separations, drug delivery, genetic science. Biocompatible polyelectrolytes also utilized biosensors biomolecular recognition systems. Layer-by-layer (LbL) technique can produce polyelectrolyte multilayer. Severe substrate gold, quartz, silicon, glass, plastic, stainless steel LbL technique. is reproducible, cost-effective, environmentally-friendly method. The characteristic of depend on the interaction between electrostatic forces. degree polymer charge modify interactions. We examine scaling theory according Gennes et al. Beurle Nogovitsin this chapter. After having discussed theory, we provide basic introduction neutron scattering dynamic light scattering. In end, analyzed biopolymers ionomers briefly.
