摘要： High density compounds that can be used in extrusion-based 3D printing processes and methods for making the same are described. The high-density compounds can be made in the form of filaments by providing a thermoplastic material (such as ABS), providing a source of heavy metal (such as Bi2O3 powder), compounding the thermoplastic material and the heavy metal source to form high-density compound, and then extruding the high-density compound to form the filament shape. These filaments can be used to make a high-density product by melting the filaments in the printing head of a FDM 3D printer and then depositing the molten material in the 3D printer in successive layers to form the high-density product. The resulting high-density products exhibit an enhanced radiopacity because of the presence of the heavy metal, allowing the rapid manufacturing of radiation shielding components via the 3D printing process. Other embodiments are described.

摘要： The present invention relates to metal coated nano-fibres obtained by a process that includes electrospinning and to the use of said metal coated nano-fibres. The process is characterised in that a polymer nano-fibre with functional groups providing the binding ability to a reducing reagent is prepared by electrospinning at ambient conditions. Then this is contacted with a reducing agent, thereby opening the epoxy ring on the surface of polymer nano-fibre and replacing with the reducing agent and the reducing agent modified film is reacted with metal solution in alkaline media. Finally the electrospun mat is treated with water to open the epoxy rings in the structure and crosslinking the chains to provide integrity.

摘要： Elastomeric materials such as elastomeric nonwoven webs of elastomeric meltblown fibers, elastomeric films or elastomeric molded materials are attained by forming, e.g., extruding or meltblowing, a polystyrenic poly(ethylenebutylene) thermoplastic block copolymer at elevated temperatures of at least about 290 degrees Centigrade, e.g., from about 290 degrees Centigrade to 345 degrees Centigrade. The resulting products retain good elastic elongation and strength properties. In the case of elastomeric nonwoven webs of elastomeric fibers, other fibers such as cellulosic fibers, e.g., cotton fibers, may be combined with the elastomeric fibers by known methods to provide an elastomeric nonwoven web comprising a blend of the elastomeric fibers with other fibers. Such web or film materials are useful generally in applications utilizing webs or sheets of elastic fabrics or the like, for example, in making composite materials in which an elastic layer of material is bonded to a gatherable web.
