Abstract
Solid particles bearing zwitterionic functional groups exhibit properties unlike other functionalized particles, and are particularly useful as proton-conductive fillers in membranes for fuel cells, where they increase physical properties as well as charge conducting properties. The particles are prepared by reacting functionalized particles with zwitterionic group-containing silanes or siloxanes.
