Dynamic of organic species in organo-clay/polypropyrene composite by quesi-elastic neutron scattering

Dynamics of a fluoromica (ME100) cation exchanged for dioctadecyl dimethyl ammonium ion (DODA$$^{+}$$)/ polypropylene composite was analyzed by quasi elastic neutron scattering (QENS), besides XRD and DSC. The QENS spectra for the DODA-ME100 at low Q=2.75 nm$$^{-1}$$ were not changed even at temperature higher than 445 K, the melting point of DODA$$^{+}$$. The results suggested the long range ($$>$$ 2 nm) molecular motions in interlayer space are restricted due to the rigid silicate layers and the strong electrostatic interaction between DODA$$^{+}$$ and the ME100. Elastic intensity scan results suggested that a little amount of motion of the polymer chains in the composite was also restricted in the molten state at 445 K. The QENS is expected to be one of the useful tools for studying the composite materials.
