20140357559 | Interpenetrating Polymer Network Hydrogel - A strain-hardened interpenetrating polymer network (IPN) hydrogel is provided. The interpenetrating polymer network hydrogel is based on two different networks.

The second network is a non-silicone network of ionizable monomers. The second network has been polymerized and chemically cross-linked in the presence of the first network and has formed physical cross-links with the first network. An aqueous salt solution having a neutral pH is used to ionize and swell the second network in the interpenetrating polymer network. The swelling of the second network is constrained by the first network, and this constraining effect results in an increase in effective physical cross-links within the interpenetrating polymer network, and, in turn, an increase its elastic modulus. The strain-hardened interpenetrating polymer network hydrogel is attractive and useful for medical, industrial, and personal hygiene purposes. | 12-04-2014 |

20100174021 | Three-dimensionally shaped interpenetrating network hydrogels - Three-dimensionally (3-D) shaped interpenetrating double network (IPN) hydrogel based on a first network and a second network are provided. The 3-D shape is characterized by a non-uniform distribution of the second network (e.g. carboxylic acid groups) when in hydrated state. The 3-D shape can further be characterized by changes in the radius of curvature of the shape. The 3-D IPN hydrogel is created by applying a non-uniform illumination pattern to polymerize the second network of monomers within a layer of a first network. In hydrated state, the second network causes a swelling force that is resisted by the first network. The non-uniformal distribution of the second network with the first network is responsible for the 3-D of the resulting IPN. The invention can find use in ophthalmic applications as well as non-ophthalmic applications. | 07-08-2010 |
