Title

Effects of star polymer functionality on the entanglement tube dilatation of the linear matrix in all-polymer nanocomposites.

Abstract

Our previous IN15 experiments show indications of disentanglement upon incorporation of small stars to an entangled polymer melt. Complementary dielectric spectroscopy studies in a wide concentration range reveal a strong effect of the functionalization (number of arms) of the stars on the disentanglement time of the matrix, and suggest exploring with NSE mixtures with higher star concentrations to provide robust microscopic evidence for the importance of the interface amount on the entanglement tube dilation. SANS experiments are crucial to precisely determine the form factor and thereby the chain dimensions of the macromolecules in the mixtures;an information also needed for the proper interpretation of the dielectric results.
