Dynamics of Water Confined in Synthetic Saponite Clays
SA Prabhudesai, VK Sharma, D Chakrabarty… - AIP Conference …, 2011 - pubs.aip.org
The dynamics of water in two synthetic saponite clays (treated by microwave) with different
interlayer spacing has been studied using the quasielastic neutron scattering technique. A
model in which the molecules undergo random jump diffusion describes the dynamics of
water in both clays. The dynamics of water confined in both saponite clays considered here
is found to be hindered in comparison to the bulk phase. It is found that diffusivity increases
for samples having higher interlayer spacing.
