hygroscopic
含义: Readily absorbing moisture from the surrounding atmosphere. Used in chemistry and materials science to describe substances that attract and hold water molecules from the air.
Hygroscopic materials can absorb enough atmospheric moisture to dissolve in it, a process called deliquescence. This property is critical in pharmaceutical manufacturing, food storage, and the handling of chemical reagents, where exposure to humidity can degrade products. Common hygroscopic substances include silica gel, table salt, and many fertilisers. The term is distinct from hydrophilic, which refers to affinity for liquid water rather than atmospheric moisture.
