title: NMR microscopy of polyacrylamide hydrogel.
abstract: Polyacrylamide Hydrogel (PAMG) is a kind of water-absorbing functional material. It has the ability of absorbing large amounts of water and releasing water under different conditions. So PAMG has an extensive background of applications in many fields. It is an interesting problem to clarify the distribution and status of water in PAMG1. This paper reports experiments in which the proton distribution and structures of networks in gamma-irradiation crosslinked PAMG samples have been shown by using spin-echo single-slice imaging of nuclear magnetic resonance microscopy.
