LIG 1

Caption

Rice University scientists are making 3-D laser-induced graphene (LIG) foam through an automated process that begins by turning the top layer of a polyimide (PI) sheet into graphene (top), stacking another layer on top (center) with ethylene glycol (EG) as a binder and then burning the top layer's PI into graphene as well (bottom). The process is repeated as necessary to build up a 3-D block that can be shaped.
