Abstract
A double network hydrogel consists of a first network and a second network, where the first network is, or includes, a first polymer that is formed, at least in part, of —CH2—CH(OH)— units, and the second network is, or includes, a second polymer that is formed, at least in part, of carboxyl (COOH)-containing units or salts thereof, sulfonyl (SO3H)-containing units or salts thereof, and at least one of hydroxyl (OH)-containing units or amino (NH2)-containing units, where the hydrogel may be used as a cartilage replacement.
Claims16
A double network hydrogel comprising a first network and a second network, the first network comprising a first polymer comprising —CH2—CH (OH)— units;
- the second network comprising a second polymer comprising carboxyl (COOH)-containing units or salts thereof, sulfonyl (SO3H)-containing units or salts thereof, and hydroxyl (OH)-containing units derived from N-(tris(hydroxymethyl)methyl)acrylamide, wherein the first polymer is non-identical to the second polymer, and where the first network is in combination with the second network so as to form the double network hydrogel.
