High-quality silver (Ag) nanowires with specific dimensions were synthesized by a polyol method with detailed control of the synthesis conditions. For the same amount of AgNO3, the Ag nanowire density became higher as the nanowire diameter decreases and the length increases. This trend was replicated in Ag nanowire films coated on poly(ethylene terephthalate) films and higher densities of Ag nanowires and their junctions were observed in thinner and shorter nanowire networks. Nanowire films with a low sheet resistance (<100 Ω sq-1) and a high transmittance (>90%) resulted from thin, long Ag nanowires. A modified percolation model, which emphasized the importance of the nanowire junction density, was in good agreement with the experimental observations. Meanwhile, long Ag nanowires were found to be undesirable in respect of their uniform coating over a large area. These results offer important design rules of Ag nanowires for highly conductive and transparent nanowire films. © 2014 Acta Materialia Inc.

This work demonstrates highly stretchable conductive blends of poly(3,4-ethylene dioxythiophene) (PEDOT) and poly(ether-b-ester)(PEEA), in which poly(ionic liquid)s (PIL) are utilized as the compatibilizing template for PEDOT. PIL-modified PEDOT (PEDOT:PIL) inherited the advantageous properties of PILs such as easy control of hydrophobicity by selecting appropriate combination of cations and anions in PIL, and thus PEDOT:PIL can be readily mixed with the PEEA on the molecular scale. The PEDOT:PIL/PEEA blends show a low percolation threshold of conducting PEDOT in PEEA and a good elastomeric mechanical properties in a way that substantial sheet resistance values of the blend remains even when the blends are stretched by 350%. © 2010 Elsevier B.V.

A practical route to the production of solution phase transferable graphene sheets using ionic liquid polymers (PIL) as a transferring medium is developed. Chemically converted graphene sheets decorated with PIL were found to be stable against the chemical reduction and well dispersed in the aqueous phase without any agglomeration. Upon the anion exchange of the PIL on graphene sheets, these PIL-modified graphene sheets in aqueous phase are readily transferred into the organic phase by changing their properties from hydrophilic to hydrophobic. © 2010 American Chemical Society.

A practical method to fabricate SWNT-conducting polymer nano-composites through poly(ionic liquid)-mediated process is developed. It is demonstrated that the poly(ionic liquid) layer along and around SWNT not only gives the facility for good dispersion of SWNT, but also provides a functionality to interlink SWNT with conducting polymers. © 2010 Wiley-VCH Verlag GmbH&Co.

We report on a polyol synthesis of highly branched hybrid crystals of Ag and AgCl (Ag:AgCl) using ionic liquid of 1-butyl-3-imidazolium chloride as a precursor and an efficient shape controlling agent. By rationally varying the concentration of ionic liquid, we achieved the control over structure and morphology of Ag:AgCl hybrid crystals in a way to have multi-arms grown from the corners of cubic seed particles. The formation of Ag:AgCl octapods relies on the preferential overgrowth on {1 1 1} facets of cubic seeds, enabled by the selective adsorption of imidazolium-based ionic liquids on {1 1 0} facets. The obtained Ag:AgCl octapods exhibited enhanced photocatalytic activity for degradation of methylene blue under visible light irradiation, compared with those with cubic morphologies. © 2014 Elsevier B.V.

Abnormal bright or dark spot images are classified into one of the LCD failures. We report here that this comes from the liquid crystal orientation, which is affected by the static charge-induced electric field. Based on the proposed mechanism, its prevention method will be discussed in terms of materials and ionizers.

The present invention relates to a method of preparing silver nanowires having a diameter of less than 100 nm and a length of 10 m or more, and, more particularly, to a method of uniformly preparing silver nanowires having a high aspect ratio using an ionic liquid as an additive in addition to a silver salt precursor, a reducing solvent and a capping agent in a polyol process. When the technology of the present invention is used, silver nanowires having a diameter of less than 100 nm and a length of 10 m or more can be uniformly prepared. Further, when a transparent conductive film is formed by applying a silver nanowire-dispersed solution onto a base film, the transparent conductive film has a surface resistivity of 10^(1)10^(3)/ and a light transmittance of 90% or more to the base film.

This invention relates to an antistatic cover tape for a carrier tape, including a sealing layer, wherein the antistatic cover tape has irregularities at a surface portion which comes into contact with an object which is transported by the carrier tape, and the sealing layer is formed only on a portion which does not come into direct contact with an object.

This invention relates to novel capping agents for manufacturing silver nanowires having a diameter of less than 100 nm and a length of 5 m or more and, more specifically, to a method of manufacturing silver nanowires and silver nanowires manufactured thereby, wherein the silver nanowires are imparted with a large aspect ratio by using vinylpyrrolidone-co-vinylimidazole copolymers (PIC) as novel capping agents in place of existing capping agents when the silver nanowires are synthesized by mixing and heating (polyol method) a silver salt precursor, a reducing solvent (a reduction agent), and a capping agent. The use of this technique enables the easy synthesis of silver nanowires having a diameter of less than 100 nm and a length of 5 m or more, with almost no granular silver particles formed during synthesis.

A transparent electrode film is manufactured by applying a transparent electrode material such as a conductive polymer, carbon nanotubes, graphene or metallic nanowires on the surface of a transparent substrate such as polyester, etc., wherein, in order to reduce changes in the surface resistance of the transparent electrode film during edge testing, photocurable resin layers are formed on both surfaces of the substrate film, and a transparent electrode layer is formed on the surface of either of the resin layers. This technique involves adjusting the degree of photocuring of the photocurable layers formed on both surfaces of the substrate film such that the degree of curing of the photocurable layer on one surface is at least 85%, and the degree of curing of the photocurable resin layer on the other surface falls in the range of 45 to 85% and then the transparent electrode layer is formed thereon.
