Cold neutron transmission for the in-situ analysis of the gas diffusion in polymers Martín de León, Judit Cimavilla Román, Paula Bernardo García, Victoria Solorzano Quijano, Eusebio Kardjilov, Nikolai Rodríguez Pérez, Miguel Ángel Producción Científica 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. 2021-08-26T09:53:59Z 2021-08-26T09:53:59Z 2021 info:eu-repo/semantics/article The Journal of Supercritical Fluids, 2021, vol. 177, 105331 0896-8446 https://uvadoc.uva.es/handle/10324/48113 10.1016/j.supflu.2021.105331 eng https://www.sciencedirect.com/science/article/pii/S0896844621001716?via%3Dihub info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2021 The Authors Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier SI
