Abstract: A double network hydrogel including a polymer (A) having a persistence length between 10 and 1000 nm; a flexible polymer (B), wherein the persistence length is measured according to single molecule force microscopy measurement, wherein polymer (B) has an extended coil conformation at a first condition and a collapsed globular conformation at a second condition. Polymer (A) preferably is a polyisocyanate, while polymer (B) is a crosslinked flexible polymer like for example PNIPAM. A method for making a double network hydrogel.
