Polymer dynamics in one component nanocomposites (OCNC)
Polymer nanocomposites display superior viscoelastic and mechanical properties compared to the corresponding pure melt. One component nano composites (OCNC) consisting of polymer grafted nano particles only, overcome the dispersion problem of conventional polymer nano composites (PNC) and promise among others superior mechanical properties. We follow up an experiment by Mark et al., who has shown that grafting leads to chain confinement even in the Rouse regime where entanglements between chains are not formed. In the proposed experiment we want to go one step further and find out, how grafting caused chain confinement interplays with the tube confinement that in long chain polymer melts leads to reptation. We conjecture that the combined action of both confinement types is at the origin of the excellent mechanical properties of OCNC.
