The relative diffusivities obtained for a wide variety of systems can be described by an exponential decay depending on a parameter that differs from that employed for rigid gels. The mathematical expression derived here can approximately predict the diffusivity in flexible gels if steric hindrance is the mechanism ruling diffusion.}, organization = {Consejeria de Economia, Conocimiento, Empresas y Universidad, Junta de Andalucia, Programa Operativo FEDER Andalucia 2014-2020 PY20_00138}, organization = {Junta de Andalucia}, organization = {European Commission SOMM17/6105/UGR}, organization = {Instituto de Salud Carlos III Spanish Government European Commission PGC2018-098770-B-I00 PID2020-116615RA-I00}, publisher = {Royal Society of Chemistry}, title = {Universal description of steric hindrance in flexible polymer gels}, doi = {10.1039/d1cp02113c}, author = {Quesada Pérez, Manuel and Maroto Centeno, José Alberto and Ramos Tejada, María del Mar and Martín Molina, Alberto}, }
