The Interaction between Water and Hydroxyl-Containing Polyimide

The Interaction between Water and Hydroxyl-Containing Polyimide

The specific interaction between aromatic polyimide with a hydroxyl group in a diamine fragment and water is studied by means of sorption and NMR relaxation spectroscopy. The influence of the molecular mobility of water and polymer on spin–spin and spin–lattice relaxation processes in the polyimide–...

Zusammenfassung:The specific interaction between aromatic polyimide with a hydroxyl group in a diamine fragment and water is studied by means of sorption and NMR relaxation spectroscopy. The influence of the molecular mobility of water and polymer on spin–spin and spin–lattice relaxation processes in the polyimide–H 2 O and polyimide–D 2 O systems is considered.
