One aspect of the invention is a compound of formula (I) [in-line-formulae]Ro-[L-(CqH2qS)pCrH2rRf]2??(I)[/in-line-formulae] wherein Ro is a divalent organic group having 2 to 40 carbon atoms; L is a linking group selected from —NHC(O)NH— or —C(O)NH— wherein the left side of the linking group is bonded to Ro; p is an integer of 0 or 1; q is an integer of 2 to 10; r is an integer of 1 to 10; and Rf is a linear or branched C1-C6 perfluoroalkyl group. Other aspects of the invention are a composite structure comprising a porous support and a porous nanoweb comprising fibrous structures comprised of one or more compositions of formula (I) and a method for making said composite structures.
