General description
Poly (Sodium 4-Styrenesulfonate) (PSS), a strong anionic polyelectrolyte, possesses a number of negative charges along its backbone chain. The ionic charges, in such electrolytes, are largely independent of the pH condition. PSS deposition exhibits layer by layer assembly. Alternate adsorption of polycations and polyanions by electrostatic attraction forms polyelectrolyte multilayers (PEMs). PSS-graphite oxide shows high performance of electric double layer capacitance compared to pristine graphite oxide on account of the layer by layer assembly. PSS coating on nanoparticles inhibit formation of agglomeration.
