Rewritable and shape-memory soft matter with dynamically tunable microchannel geometry in a biological temperature range†
Abstract
Here we present on-demand switchable microchip materials that display potent rewritable and shape-memory properties which are shown to contribute to fluidic control as pumps and valves. Semi-crystalline poly(ε-caprolactone) (PCL) was chemically crosslinked to show shape-memory effects over its melting temperature (Tm) because the crosslinking points set the permanent shape and the crystalline domains serve as thermally reversible
