  • Patent number: 10490411
    Abstract: Embodiments described herein generally relate methods for selective deposition of carbon structures. In one embodiment, a method includes forming energized carbon species in a process chamber, diffusing the energized carbon species through a metal layer, wherein the metal layer is disposed on a first surface of a first material that is coplanar with a second surface of a second material, and forming a carbon structure between the first surface of the first material and the metal layer from the energized carbon species. Because the carbon structure is selectively deposited on the first surface and self-aligned to the first material, the possibility of overlay or misalignment of subsequent device layers formed on the first surface of the first material after the removal of the carbon structure is significantly reduced.

  • Patent number: 9587089
    Abstract: Conventional toughening agents are typically rubbery materials or small molecular weight molecules, which mostly sacrifice the intrinsic properties of a matrix such as modulus, strength, and thermal stability as side effects. On the other hand, high modulus inclusions tend to reinforce elastic modulus very efficiently, but not the strength very well. For example, mechanical reinforcement with inorganic inclusions often degrades the composite toughness, encountering a frequent catastrophic brittle failure triggered by minute chips and cracks. Thus, toughening generally conflicts with mechanical reinforcement. Carbon nanotubes have been used as efficient reinforcing agents in various applications due to their combination of extraordinary mechanical, electrical, and thermal properties.

  • Patent number: 8685178
    Abstract: A method of preparing metal-modified silica particles is disclosed. Specifically, a treatment chamber is provided in which a first and a second formulation are ultrasonically mixed to prepare metal-modified silica particles. The treatment chamber has an elongate housing through which the first and second formulations flow longitudinally from a first inlet port and a second inlet port, respectively, to an outlet port thereof. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency to ultrasonically energize the formulations within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other.

    Abstract: Disclosed are methods or manufacturing a metal wiring buried flexible substrate by using plasma and flexible substrates manufactured by the same. The method includes pre-treating a substrate by irradiating the plasma on the surface of the substrate (Step 1), forming a metal wiring on the pre-treated substrate in Step 1 (Step 2), forming a metal wiring buried polymer layer by coating a curable polymer on the substrate including the metal wiring formed thereon in Step 2 and curing (Step 3), and separating the polymer layer formed in Step 3 from the substrate in Step 1 (Step 4), The metal wiring may be inserted into the flexible substrate, and the resistance of the wiring may be decreased. The metal wiring may be clearly separated from the substrate, and impurities on the substrate surface may be clearly removed. The flexible substrate may be easily separated by applying only physical force.

  • Publication number: 20130101792
    Abstract: The present invention solves numerous problems in state-of-the-art industrial polymer shaping of micro and nanostructures. The problems of high tool polishing requirements, the inability to define an arbitrary topographical structure on an arbitrary free-form (curved) surface, limited durability and replication quality, as well as providing a convenient method for functionalizing the surface. The invention solves these problems by deploying a ceramic material precursor, which may be coated onto a conventional polymer shaping tool, micro- or nanostructured by mechanical contact (embossing), cured into a hard, durable ceramic material comprising the desired structures. The ceramic material is functionalisable by silane chemistry, due to its high surface density of —OH groups. This apparatus may then be used in a conventional polymer shaping process to make nanostructured polymer replicas.
