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.

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.

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.

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.

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
