Thermoreversible hydrogels based on amphiphilic block copolymers have been widely investigated in the past. Primarily, this research has focused on systems that are liquid at room temperature but gel upon heating close to physiological temperature since this allows application as in-situ gelling biomaterials. In contrast, amphiphilic block copolymer solutions that gel upon cooling have been only rarely described in literature. This may be due to the narrow application window of such polymers, but can arguably also be attributed to the lower prevalence of suitable materials. However, polymer solutions that gel upon cooling might be of interest as rheology modifiers , for temperaturetriggered (drug) release , as suspension media for gel-in-gel printing, or for the generation of perfusable channels .
