Thermoresponsive Hydrogels Bend
12 May 2008, 13:39

Categories: smt-polymorphic-shape-shifters gels--foams

Researchers at Osaka University, Japan, have created pore-gradient hydrogels that bend in response to changes in temperature. Their ability to bend is the result of a deswelling (i.e., shrinking) property of PNIPAAm hydrogels containing silica particles. During tests, the gels transitioned from flat (Angle = 180º) at 20ºC to bent (Angle = 30º) at 40ºC, all within 60 seconds.
