摘要: Additive manufacturing processes, such as fused filament fabrication, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of a printed object. Conductive traces and similar features may be introduced in conjunction with fused filament fabrication processes by incorporating a metal precursor in a polymer filament having a filament body comprising a thermoplastic polymer, and forming a printed object from the polymer filament through layer-by-layer deposition, in which the metal precursor remains substantially unconverted to metal while forming the printed object. Suitable polymer filaments compatible with fused filament fabrication may comprise a thermoplastic polymer defining a filament body, and a metal precursor contacting the filament body, in which the metal precursor is activatable to form metal islands upon laser irradiation.

摘要: An electrochemical device is disclosed, which may include an anode, a cathode, and a molded electrolyte composition disposed between the anode and the cathode. Implementations of the electrochemical device may include where the cathode and/or the anode are disposed in a stacked geometry. The electrolyte composition may include a gel polymer electrolyte, which can include a hydrogel of a copolymer and a salt dispersed in the hydrogel of a copolymer. The electrolyte composition may alternatively include a crosslinker or a photoinitiator. A method of producing an electrolyte layer of an electrochemical device is also disclosed, including preparing a substrate having an electrode for an electrochemical device, preparing a gasket to form a cavity on the substrate for the electrolyte layer, and depositing an electrolyte composition onto the substrate

摘要: Additive manufacturing processes featuring consolidation of thermoplastic particulates may form printed objects in a range of shapes. Inorganic nanoparticles disposed upon the outer surface of the thermoplastic particulates may improve flow performance of the thermoplastic particulates during additive manufacturing, but may be undesirable to incorporate in some printed objects. Polymer nanoparticles may be substituted for inorganic nanoparticles in some instances to address this difficulty and provide other advantages. Particulate compositions suitable for additive manufacturing may comprise: a plurality of thermoplastic particulates comprising a thermoplastic polymer and a plurality of polymer nanoparticles disposed upon an outer surface of the thermoplastic particulates, the polymer nanoparticles comprising a crosslinked fluorinated polymer.

摘要: Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of printed objects. Conductive traces and similar features may be introduced during additive manufacturing processes by incorporating a metal precursor in a thermoplastic printing composition, converting a portion of the metal precursor to discontinuous metal islands using laser irradiation, and performing electroless plating. Suitable printing compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer, a metal precursor admixed with the thermoplastic polymer, and optionally a plurality of nanoparticles disposed upon an outer surface of each of the thermoplastic particulates, wherein the metal precursor is activatable to form metal islands upon exposure to laser irradiation. Melt emulsification may be used to form the thermoplastic particulates.
