Abstract
Use of dry electrolytes to polish metal surfaces through ion transport. A conductive liquid of the dry electrolyte includes at least a sulfonic acid. According to one embodiment, the porous particles of the dry electrolyte include sulfonate polymer, such as, polystyrene divinylbenzene. According to one embodiment, the conductive liquid of the dry electrolyte includes methane-sulfonic acid. Preferably, the concentration of the sulfonic acid in relation to the solvent is ranging from 1 to 70%. Optionally, the conductive liquid of the dry electrolyte includes a complexing agent and/or a chelating agent.
Claims7
A plurality of free solid bodies that each comprises a porous particle containing an electrically conductive liquid in an amount below a saturation point of the porous particle, the electrically conductive liquid comprising a sulfonic acid.
