  • Publication number: 20240010854
    Abstract: The present invention relates to a composition for coating a carbon nanomaterial, comprising a bipolar compound, an amine-based dispersant, and a solvent. Unlike conventional coating solutions using an ionic dispersant, the composition for coating a carbon nanomaterial of the present invention is used together with a polymer-based dispersant to reduce the cost incurred during the coating, and the coating is completed within minutes, thereby reducing the coating time. In addition, unlike the conventional coating solutions that require drying at a temperature of 150° C. or higher, the coating composition of the present invention can be dried at a low temperature, which can save time and cost required for coating.

  • Patent number: 11828070
    Abstract: A fire and disaster evacuation apparatus installed in a high-rise building includes a stationary frame; a front plate; a side plate; a bottom; a locking device; and a lever part, and its width is less than a thickness of an outer wall of the building. The apparatus can be mounted integrally with an outer wall of an apartment or a building and thus it can be mounted without changing the exterior of the building. The apparatus is formed in a thin structure so that it can be mounted at any place as long as an outer wall is 160 mm or more, and is located inside a wall body so that it does not affect the exterior of the building, and so that additional power is not necessary to drive the apparatus.

  • Patent number: 5644015
    Abstract: The present invention relates to a process of producing a polymer suitable for manufacturing spandex filament having remarkable elastic recovery rate and heat-setting efficiency wherein the process comprises: stirring a mixture of a glycol and a diisocyante, where the molar ratio of diisocyanate to glycol is 1.5 to 1.64, in a homogenizer at about 40.degree. to about 50.degree. C. and reacting said mixture to give a first polymer containing less than 4 mole % of unreacted diisocyanate; then, reacting said polymer with a chain-extender mixture containing ethylenediamine, 1,2-diaminopropane, and diethylenetriamine, preferably, about 74 to about 80 mole % of ethylenediamine, about 19 to about 25 mole % of 1,2-diaminopropane and about 0.2 to about 0.8 mole % of diethylenetriamine. Elastic polyurethaneurea-based spandex filament is produced by dry-spinning the polymer.
