Abstract

The present invention relates to (i) novel fluoroionic compounds capable of dispersing particulate filler compositions into a fluoropolymer; (ii) novel particulate compositions in which particulates are surface-functionalized with a fluoroionic compound; (iii) fluoropolymer composite materials containing the surface-functionalized particulates of (ii) incorporated into a fluoropolymer; (iv) crosslinked versions of (iii); v) methods for producing the crosslinked material of (iv); and (vi) articles of manufacture containing the compositions (iii) and (iv).
