COMPONENT DYNAMICS IN AN ALL-POLYMER NANO-COMPOSITE BASED ON SINGLE-CHAIN NANO-PARTICLES
The (few) investigations carried out until now suggest that the addition of single-chain nano-particles (SCNPs) to long linear polymer chains induces their disentanglement. Surprisingly, in an all-polymer nano-composite where the linear chains in the matrix are precursors of the SCNPs (and therefore their segmental dynamics are identical) we observe, together with tube dilation, an acceleration of the initial decay of the dynamic structure factor of the chains. With these experiments we want to selectively investigate the component dynamics in this all-polymer nano-composite at segmental level, trying to shed light on this unexpected result.
