Abstract
A nanocomposite is formed from at least one copolymer and at least one nanofiller. The copolymer is formed of units derived from isoolefins having from 4 to 7 carbon atoms and multiolefins. The nanofiller comprising a surfactant wherein the surfactant has the structure of (R1R2R3R4)N+ wherein R1 is benzyl derived unit, which may or may not be substituted, wherein R2 is selected from C1 to C26 alkyls, C2 to C26 alkenes, and C3 to C26 aryls, and wherein R3 and R4 are the same or different and are independently selected from C9 to C26 alkyls, C9 to C26 alkenes, and C9 to C26 aryls.
