AC Electrokinetics of Salt-Free Multilayered Polymer-Grafted Particles

Abstract: Interest in the electrical properties of the interface between soft (or polymer-grafted) nanoparticles and solutions is considerable. Of particular significance is the case of polyelectrolyte-coated particles, mainly taking into account that the layer-by-layer procedure allows the control of the thickness and permeability of the layer, and the overall charge of the coated particle. Like in simpler systems, electrokinetic determinations in AC fields (including dielectric dispersion in the 1 kHz–1 MHz frequency … Show more

“…3 and 4 , surface agents can change this phase difference, and the real part of relative permittivity becomes positive. This can be directly resulted from the fact that the effective permittivity of the decorated particle is no longer like an ideal metal, and the particle has moved away from its metallic properties [ 45 , 46 ].…”
