  • Patent number: 11857926
    Abstract: A nanocarbon separation apparatus includes: an electrophoresis tank; electrodes disposed in an upper part and a lower part of the electrophoresis tank; a first injection port through which a liquid is injected into the electrophoresis tank; a second injection port which is provided below the first injection port and through which a liquid having a pH lower than a pH of the liquid injected through the first injection port is injected into the electrophoresis tank; and a recovery port provided in a surface facing a surface having the first injection port and the second injection port, wherein the liquid injected through at least one of the first injection port and the second injection port is a dispersion liquid having nanocarbons dispersed therein.
    Type: Grant

  • Patent number: 11511229
    Abstract: A nanocarbon separation method includes: a step of preparing a plurality of liquids with different specific gravities in which at least one of the plurality of liquids is a dispersion liquid in which a mixture of nanocarbons with different properties is dispersed; a step of sequentially injecting the plurality of liquids into an electrophoresis tank so that the specific gravities of the liquids decrease from a bottom to a top of the liquids in a direction of gravitational force; and a step of separating the mixture of the nanocarbons by moving a part of the mixture toward an electrode side disposed in an upper part of the electrophoresis tank and moving a remainder of the mixture toward an electrode side disposed in a lower part of the electrophoresis tank by applying a direct current voltage to the electrodes.

  • Publication number: 20040068972
    Abstract: A conjugated yarn is provided which is capable of preventing a high-tenacity fiber used therein from being ruptured during a weaving or knitting process. The conjugated yarn includes: core yarns each having a high-tenacity fiber and a reinforcing fiber positioned parallel with the high-tenacity fiber for reinforcing the high-tenacity fiber; and a tying yarn bundling the core yarns. Also provided is a fiber reinforced plastic of which the strength and safety are improved by the use of the conjugated yarn.
