Abstract
Curable compositions that include at least one fluorinated elastomeric gum; and nanoparticles functionalized with at least one compound according to formula (I): X—(CF2)n—(O)p—(CH2)m—Si—Y3 w X is Br, I, CF2═CF—O—, CH2═CHCH2—O—, CH2═CHCH2—, or CH2═CH—, n is an integer from 2 to 8, m is an integer from 2 to 5, p is 0 or 1, and Y is Cl— or —OR, where R is a linear or branched alkyl having 1 to 4 carbon atoms. In some embodiments, Y is —O(CH2)xCH3, where x is an integer from 0 to 3.
