Electric double layer force
WebSuspended particles have an electric surface charge, strongly affected by surface adsorbed species, on which an external electric field exerts an electrostatic Coulomb force. According to the double layer theory, all surface charges in fluids are screened by a diffuse layer of ions, which has the same absolute charge but opposite sign with ... Webconstants in the Stern layer and in the diffuse layer, respectively. The dielectric constant in the Stern layer is different from that in the diffuse layer, and the dielectric constant in the …
