Polymer Chain Mobility in Polyelectrolyte Multilayers1, "Высокомолекулярные соединения. Серия С"

Abstract-Free-standing polyelectrolyte multilayer membranes have been formed by the layer-by-layer technique using a dip-coating apparatus. The polymer-chain mobility has been studied by 1H relaxation in the rotating frame T1rho NMR with 13C chemical shift resolution. For each of the individual polymers a single relaxation component has been observed for all resolved signals. In the multilayer a significantly different relaxation time T1rho has been observed with a minor second component. The interaction between the oppositely charged polyelectrolytes influences the molecular mobility.
