摘要： A freeform fabrication process and apparatus for making a colorful 3-D object. The process includes (1) operating a multiple-channel droplet deposition device for supplying and, on demand, ejecting droplets of multiple liquid compositions containing a solidifiable baseline body-building material and different colorants; (2) providing a support platform a distance from this deposition device to receive the droplets therefrom; and (3) during the droplet ejecting process, moving the deposition device and the platform relative to one another in an X-Y plane and in a Z direction orthogonal to the X-Y plane so that the droplets are deposited to form multiple layers to build a colorful 3-D object. These steps are executed under the control of a computer system by taking additional steps of (4) creating a geometry and color pattern of the object on a computer with the geometry including a plurality of color-coded segments defining the object; (5) generating programmed signals corresponding to each of the segments in a predetermined sequence; and (6) moving the deposition device and the platform relative to each other in response to these programmed signals. Preferably, the system is also operated to generate a support structure for any un-supported feature of the object.

摘要： Provided is a process for producing an electrolyte-impregnated laminar graphene structure for use as a supercapacitor electrode. The process comprises (a) preparing a graphene dispersion having multiple isolated graphene sheets dispersed in an electrolyte; and (b) subjecting the graphene dispersion to a forced assembly procedure, forcing the multiple graphene sheets to assemble into an electrolyte-impregnated laminar graphene structure, wherein the multiple graphene sheets are alternately spaced by thin electrolyte layers, less than 5 nm in thickness, and the graphene sheets are substantially aligned along a desired direction, and wherein the laminar structure has a physical density from 0.5 to 1.7 g/cm3 and a specific surface area from 50 to 3,300 m2/g, when measured in a dried state of the laminar structure with the electrolyte removed. This process leads to a supercapacitor having a large electrode thickness, high active mass loading, high tap density, and exceptional energy density.
