    摘要: The present invention relates to an organic luminescent material/clay nanocomposite with improved luminescent efficiency and stability, which is prepared by blending an organic luminescent material with a nanoclay, and an electroluminescent device employing the same. The electroluminescent device of the invention comprises: a transparent substrate; a semitransparent electrode deposited on the transparent substrate; a clay nanocomposite emissive layer spin-coated with an organic EL material/clay nanocomposite, positioned on the semitransparent electrode; and, a metal electrode deposited on the clay nanocomposite emissive layer. Since the electroluminescent device of the invention provides improved luminescent efficiency and stability, it can be practically applied to the development of organic semi-conductor.

    摘要: The present invention provides ionomer-type emissive polymer whose heat-stability is improved by the formation of ionic cross-link, and electroluminescent device employing the same as an emissive layer. The ionomer-type emissive polymer is characterized by an ionomeric conformation, which has a backbone in a conjugate, non-conjugate or conjugate/non-conjugate multi-block conformation with or without a side chain in a conjugate or non-conjugate conformation, and 0.1 to 15% (mol/mol) of ions bound to the backbone or side chain of the emissive polymer with or without linker. The electroluminescent diode employing ionomer-type emissive polymer can be applied to the preparation of long-life and electricity-saving electroluminescent display device since it can luminesce at low voltage due to its ionomeric conformation and have higher heat-stability than the conventional ones.

    摘要: Disclosed is a method of manufacturing colloidal crystals using a confined convective assembly, more particularly, to a method for manufacturing two-dimensional and/or three dimensional colloidal crystals on a substrate by infusing colloidal suspension between two substrates and self-assembling colloidal particles by capillary action. The present invention can control a convective flow moving the colloidal particles to a meniscus generated by removing the solvent of the colloidal suspension. It is possible to manufacture face-to-face two-dimensional colloidal crystals and/or three-dimensional colloidal crystals within a short time using various sizes of colloidal particles through the control of the convective flow of colloidal particles, which are not easily achieved in the existing method. The present invention can use two-dimensional colloidal crystals and/or three-dimensional colloidal crystals manufactured using the confined convective assembly method in the various fields such as in biosensors and devices, information storing medium, display devices and optical devices.

    摘要: Disclosed herein is a multiphase electrorheological fluid having an improved yield stress and stability. The multiphase electrorheological fluid comprises a first liquid phase component as a continuous oil phase; particles dispersed in the continuous oil phase; and a second liquid phase component which consists of emulsion liquid droplets and is dispersed in the continuous oil phase while being immiscible with the continuous oil phase. The dispersed liquid droplets have higher electrical conductivity and dielectric constant than those of the continuous oil phase.
