It is known that topological restraints by "chain entanglements" severely affect chain dynamics in polymer melts. In this field-cycling NMR relaxometry and fringe-field NMR diffusometry study, melts of linear polymers in bulk and confined to pores in

Proton and deuteron field-cycling NMR relaxometry of liquids confined in porous glasses

Autor: Stapf S., Kimmich R., Seitter R., Maklakov A., Skirda V.

Publikováno v: SCOPUS09277757-1996-115-SID0343113400

Polar and non-polar liquids in porous glasses have been studied by proton and deuteron field-cycling NMR relaxometry. The mean pore diameters were 4 nm, 30 nm and 208 nm. The frequency dependence of the spin-lattice relaxation time T1 is strongly inf
