Percolated interface conductivity of sheet-like electrolyte prepared from proton conductive core-shell particles and effect of core particle diameter

Abstract

Ultrathin layers of positively charged poly(diallyldimethylammonium chloride) (PDDA) and negatively charged poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) were alternately deposited on negatively charged phenylsilsesquioxane (PhSiO_3/2) particles via layer-by-layer assembly technique. A monolithic sheet-electrolyte was successfully obtained from the PAMPS-deposited PhSiO_3/2 particles by pressing at 70 MPa.Proton conductivity of the sheet composed of PAMPS-deposited particles is discussed relating to the core particles size.
