This Is The Opposite of Hydrophobic—Superhydrophilic

Sodium polyacrylate is a hydrophilic polymer that can absorb more than 100x its weight in water! It does this through an extraordinary ability to form hydrogen bonds with water molecules, due to highly charged regions on the polymer chain. This property makes it really useful for designing absorbent materials, and a primary use for sodium polyacrylate is the production of disposable diapers. Worldwide, we use more than 200,000,000 kg annually! #chemistry #chemteacherphil #hydrophilic #polymer |
