Strain-hardened interpenetrating polymer network hydrogel |
| abstract |
A strain-hardened interpenetrating polymer network (IPN) hydrogel is provided The IPN hydrogel is based on two different networks The first network is a non-silicone network of preformed hydrophilic non-ionic telechelic macromonomers chemically cross-linked by polymerization of its end-groups 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 results in an increase in effective physical cross-links within the IPN, and increases its elastic modulus The strain-hardened IPN hydrogel is useful for medical, industrial, and personal hygiene purposes |
