Title

Impact of Nano-Structuration on the alpha-Relaxation: Collective and Self-Motions of Melt Systems Composed by Single-Chain Nano-Particles

Abstract

We want to characterize the dynamic structure factor (collective motions) and the incoherent scattering function of hydrogens in bulk samples composed of single-chain nano-particles (SCNPs) in comparison to melts of the precursor (linear polymers) counterparts. In this way, we will determine the possible impact of internal cross-link on the microscopic motions involved in the dynamics of the structural relaxation. We are now in the position to face this problem thanks the availability of fully deuterated SCNPs based on THF, which in addition do not crystallise and display a very low glass-transition temperature.
