Superabsorbent polymers (SAPs) are materials that can absorb and retain large amounts of liquid relative to their own mass. They are commonly used in products like diapers, feminine hygiene products, and agricultural applications to manage moisture. SAPs can absorb water and swell into a gel-like substance, making them effective for controlling liquid in various settings. These polymers are typically made from synthetic materials, such as polyacrylate, which allows them to achieve high absorbency. When exposed to liquid, SAPs can hold many times their weight in water, making them valuable in both consumer products and industrial applications, such as water retention in soil.
