The relationship between moisture content and material viscosity varies depending on the material type. For instance, in rammed earth walls, the elastic modulus and dynamic viscosity coefficient increase as the structure dries, indicating a more viscous behavior with lower moisture content. In contrast, the addition of multiwall carbon nanotubes to epoxy resin and carbon fiber reinforced plastic reduced moisture absorption and subsequently decreased the flexural strength and modulus, leading to a less viscous response with increased moisture content. Additionally, in epoxy-clay nanocomposites, exposure to moisture altered the glass-transition temperature and the forced rubber-like elasticity, showcasing changes in material viscosity with absorbed moisture. Therefore, the impact of moisture on material viscosity is material-specific, with some exhibiting increased viscosity and others showing decreased viscosity with higher moisture levels.What is the gap in the literature on lithium-ion battery electro-thermal models?
