Sub-zero temperature mechanically stable low molecular weight hydrogels
We show here a low molecular weight hydrogelator based on a functionalised dipeptide which is stable down to temperatures of −12 °C despite being made from >99% water. With the addition of glycerol this can be lowered further to −40 °C. At these colder temperatures there is no effect on the mechanical properties of the gels.
