Reversible organohydrogels based on dynamic hydrogen bonding among water, dimethyl sulfoxide, and polyethylene glycol.

Facile gelation and degelation have been achieved by dynamic hydrogen bonding among dimethyl sulfoxide, water, and polyethylene glycol to prepare anti-freezing, drying-resistant, strongly thixotropic, and water-sensitive organohydrogels that are significant for biomaterial protection and storage.
