Abstract: In this work, we consider the effect of adding functionalized silica particles to a poly (tetramethylene oxide)-based polyurethane that is a candidate to be used as flexible storage containment for a variety military fuels. We have synthesized urethanes with silica concentrations varying from 0% to 40% by weight and evaluated the diffusion of commercial gasoline and their mechanical properties.
