Facile preparation of tough hydrogels with excellent processability is of great practical importance, but it remains a great challenge. A novel type of hydrogen-bonded supramolecular PVA-glycerol gels is prepared with a very simple physical mixing method, in which glycerol molecules connect PVA chai...
