This set-up is based on performing neutron radiography and tomography of polymeric materials under high pressures of gas. Information about the absorption kinetics of supercritical CO2 was obtained. Additionally, solubility, diffusivity, and macroscopic changes in the dimensions of the samples can be in-situ obtained through the developed measurement technique. This novel approach can be very helpful to analyze the diffusion kinetics in a wide range of polymers. eng Attribution-NonCommercial-NoDerivatives 4.0 Internacional Cold neutron transmission for the
