Hydrogels.
Applications ▼
Only Statement 1 is conventionally correct. Hydrogels are three-dimensional, highly absorbent polymer networks holding vast amounts of water. Because of their biocompatibility, they are extensively used in the medical field for controlled, sustained drug delivery, tissue engineering, and specialized wound dressings. They are not standardly used for mobile air-conditioning or heavy industrial lubricants.
