RT info:eu-repo/semantics/article T1 Cold neutron transmission for the in-situ analysis of the gas diffusion in polymers A1 Martín de León, Judit A1 Cimavilla Román, Paula A1 Bernardo García, Victoria A1 Solórzano Quijano, Eusebio A1 Kardjilov, Nikolai A1 Rodríguez Pérez, Miguel Ángel K1 Diffusion mechanisms K1 Mecanismos de difusión K1 Gas dissolutions K1 Disoluciónes de gas AB A novel set-up for monitoring the gas diffusion process in polymers has been developed. 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.
