    摘要: Provided is a simple, fast, scalable, and environmentally benign method of producing a graphene-reinforced polymer matrix composite directly from a graphitic material, the method comprising: (a) mixing multiple particles of a graphitic material and multiple particles of a solid polymer carrier material to form a mixture in an impacting chamber of an energy impacting apparatus; (b) operating the energy impacting apparatus with a frequency and an intensity for a length of time sufficient for peeling off graphene sheets from the graphitic material and transferring the graphene sheets to surfaces of solid polymer carrier material particles to produce graphene-coated or graphene-embedded polymer particles inside the impacting chamber; and (c) forming graphene-coated or graphene-embedded polymer particles into the graphene-reinforced polymer matrix composite. Also provided is a mass of the graphene-coated or graphene-embedded polymer particles produced by this method.

    摘要: The present invention includes methods of three-dimensional printing as well as the high density and/or radiopaque three-dimensional articles produced thereby. Articles prepared in accordance with the method of the present invention may be used as production articles or as prototypes to be able to demonstrate the shielding characteristics of shaped articles in instances where production articles may later be produced by injection molding. The method of the present invention may be carried out using fused deposition modeling or selective laser sintering methods known and used in the art.
