Abstract: DMA investigations on polystyrene-block-polyisoprene-block-polystyrene three block copolymer containing with 17 wt%. styrene, loaded by various amounts of multiwall carbon nanotubes are reported. The wrapping of the soft phase around the nanofiller is demonstrated through the splitting of the glass transition assigned to the soft phase. The nanofiller has a weaker effect on the hard phase (polystyrene) of the block copolymer and did not destroy completely the self-assembly features of the block copolymer as the order to disorder transition was still observed in all investigated nanocomposites. A model for the morphology of this nanocomposites is suggested.
