Inspired by mussels, researchers have harnessed DOPA\u2010metal coordination to create dynamic and mechanically responsive polymeric materials. Here, we harness the robust DOPA\u2010V interactions observed in mussels combined with the temperature\u2010responsive properties of vanadium dioxide (VO\n                    <jats:sub>2<\/jats:sub>\n                    ) to develop a room\u2010temperature process to produce thermochromic VO\n                    <jats:sub>2<\/jats:sub>\n                    hydrogels and films. 4\u2010arm polyethylene glycol (PEG) polymers functionalized with DOPA\u2010catechol moieties were mixed with VO\n                    <jats:sub>2<\/jats:sub>\n                    nanoparticles in solution. Raising pH led to formation of hydrogels, while spin coating enabled processing into thin films. Hydrogels possessed mechanically tunable viscoelasticity and self\u2010healing response. Furthermore, dried free\u2010standing films were highly flexible and exhibited plastic deformation with extensibilities of 200% and beyond, while still retaining the thermochromic properties of the nanoparticles. The facile fabrication method and the resulting versatile mechanical response combined with thermochromic properties are promising for future development VO\n
