These schematics show the printing of water in oil using a nanoparticle supersoap. Gold nanoparticles in the water combine with polymer ligands in the oil to form an elastic film (nanoparticle supersoap) at the interface, locking the structure in place. Credit: Berkeley Lab
Reconfigurable material could be used for liquid electronics and chemical synthesis, among other applications. Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to print 3D structures composed entirely of liquids. Using a modified 3D printer, they injected threads of water into silicone oil – sculpting tubes made of one liquid within another liquid.
They envision their all-liquid material could be used to construct liquid electronics that power flexible,...
