It is shown herein that it is possible to control the mechanical and microstructural properties of collagen gels by manipulating temperature in the vicinity of the sol–gel transition; the Fractional Maxwell Model is also shown to accurately describe the rheological behaviour of such gels.
The sol–gel transition and the mechanical properties of a supramolecular poly(vinyl alcohol)–iodine complex can be tuned in time thanks to an “iodine clock”.
