Composite recycling steps (IMAGE)
Caption
Researchers demonstrated easy reclamation and recycling of 94% of the liquid metal in the newly created composite material. In their demonstration, a composite sample with a functioning circuit (box 1) was dissolved in a series of chemical solutions (box 2), allowing most of the liquid metal within it to be isolated (box 3). The metal was then used to create a fresh composite sample complete with a new functioning circuit (box 4).
