Effect of Paramagnetic Fe3+ on T1H in PVA/montmorillonite-clay Nanocomposites

Abstract The relation between T1H values of PVA/montmorillonite-clay nanocomposites and an iron content in a few different kinds of montmorillonite clays is examined. The T1H values for PVA in the PVA/montmorillonite-clay nanocomposites decreased drastically with the amount of the montmorillonite clay, and the decrement depends on the iron content in the montmorillonite clay.
