hydrogelcoated
Hydrogel-coated refers to a surface or device that has a hydrogel layer applied to its exterior. Hydrogels are water-rich, three-dimensional polymer networks that swell in aqueous environments to form soft, hydrated surfaces. The hydrogel layer creates a lubricious, biocompatible interface and can influence interactions with surrounding tissues and fluids.
Common hydrogel materials used for coatings include poly(2-hydroxyethyl methacrylate) (pHEMA), polyvinyl alcohol, polyacrylamide, and poly(ethylene glycol)-based
The hydration state of hydrogel coatings provides several functional benefits. They offer low friction and improved
Applications include medical devices (such as catheters, stents, and orthopedic implants) to reduce irritation and fouling,
Key considerations for hydrogel-coated devices are mechanical durability, coating adhesion, chemical stability, and compatibility with sterilization
