Explanation:
Hydrogels are water-absorbent polymer
networks that can be used in a variety of applications, including:
Controlled drug delivery: Hydrogels can encapsulate
drugs and release them gradually over time, which can help reduce the dose and
dosing frequency and improve patient compliance.
Mobile air-conditioning systems:
Hydrogels can be used as desiccants to control humidity.
Industrial lubricants: Hydrogels can
improve the properties of industrial lubricants, such as reducing friction and
wear, controlling viscosity, and improving thermal stability.
Hydrogels are biphasic materials that are
a mixture of porous, permeable solids and at least 10% by weight or volume of
interstitial fluid composed completely or mainly by water. Many hydrogels are
synthetic, but some are derived from nature.
