ABSTRACT

Two different kinds of micro-nanoconstrained damping structure units (M-NCDSUs) were prepared by carboxyl-terminated butadiene acrylonitrile copolymer and epoxy-terminated butadiene acrylonitrile copolymer liquid rubbers intercalating organic montmorillonite, respectively. The prepared M-NCDSUs were then blended with epoxy resin to obtain damping structure integration nanocomposites. The X-ray diffraction and transmission electron microscope measurements applied for the obtained samples confirmed the good formation of M-NCDSUs in the epoxy network. The tensile strength decreased slightly with the addition of M-NCDSUs, whereas the damping properties measured by dynamic mechanical analysis showed a remarkable increase. Besides, the cured epoxy resin exhibited a two-phase morphology where the spherical rubber phase dispersed uniformly in the epoxy matrix. The nanocomposites containing M-NCDSUs showed superior comprehensive properties compared with that without the functional units. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 39797.
