Abstract:
Disclosed is a method of fabricating a metal nanowire pattern. The method of fabricating the metal nanowire pattern is characterized by, using an organic nanowire, which is fabricated by means of an electric field auxiliary robotic nozzle printer, as a template, forming a metal nanowire into a desired shape by plating a metal layer on the organic nanowire. Therefore, various metal nanowire patterns can be formed in a large area and applied to electrodes or electronic devices.
Abstract:
The present invention relates to a thermosetting resin sandwich prepreg, and the copper clad laminates and multi-layered printed circuit wiring boards manufactured therefrom. The interlayer of the thermosetting resin sandwich prepreg contains the thermosetting resin composition with a high content of fillers, and the outer layer of the prepreg contains the thermosetting resin composition with a low content of fillers. The copper clad laminates prepared by using the prepregs have good adhesion to metal foils, insulativity and uniform dielectric constant distribution.

Abstract:
An electronic device has structures such as substrates and internal housing structures. The substrates may be rigid substrates such as rigid printed circuit boards and flexible substrates such as flexible printed circuits, flexible touch sensor substrates, and flexible display substrates. Carbon nanotubes may be patterned to form carbon nanotube signal paths on the substrates. The signal paths may resist cracking when bent. A flexible structure such as a flexible printed circuit may have carbon nanotube signal paths interposed between polymer layers. Openings in a polymer layer may expose metal solder pads on the carbon nanotube signal paths. A stiffener may be provided under the metal solder pads. Polymer materials in the flexible structure may be molded to form bends. Bends may be formed along edges of a touch sensor or display or may be formed in a flexible printed circuit.

Abstract:
A fabricated substrate has at least one plurality of posts. The plurality is fabricated such that the two posts are located at a predetermined distance from one another. The substrate is exposed to a fluid matrix containing functionalized carbon nanotubes. The functionalized carbon nanotubes preferentially adhere to the plurality of posts rather than the remainder of the substrate. A connection between posts of the at least one plurality of posts is induced by adhering one end of the functionalized nanotube to one post and a second end of the functionalized carbon nanotube to a second post.
Abstract:
Identifying marks are often used for authentication and tracking purposes with various types of articles, but they can sometimes be subject to replication or removal by an outside entity, such as a person or group having malicious intent. Carbon nanotubes and other carbon nanomaterials can be used to form identifying marks that are not visible to the naked eye, thereby making the marks more difficult for an outside entity to tamper with. Various articles can include an identifying mark that is not visible to the naked eye, the identifying mark containing a nanomaterial that includes a plurality of carbon nanotubes with a registered distribution of chiralities. The registered distribution of chiralities can be further tailored to increase the level of security provided by the mark.
