摘要:
A composite metallic material 1 according to the invention is used for, e.g., electrolytic capacitors, and includes a metallic material substrate 10 and a high polymer thin layer 11 having a fine pattern 12 formed on at least one surface of the substrate 10 by self-organization. This high polymer thin film 11 is formed by, for example, drying hydrophobic organic solvent solution of high polymer compound. By subjecting this composite metallic material 1 to etching processing, etching pits are formed uniformly with high density based on the fine pattern.
摘要:
A solution having a polymer dissolved in a hydrophobic organic solvent is cast on a substrate, said organic solvent is evaporated in a moist atmosphere to condense moisture contained in an atmosphere prevailing on a surface of said cast solution into micro-droplets, said micro-droplets are dispersed on the surface of said cast solution or in said cast solution into a close-packed structure, said micro-droplets, condensed and dispersed on the surface of said cast solution or in said cast solution, are evaporated to obtain a porous honeycomb structure with said droplets used as casts, and said porous honeycomb structure is at least bisected by peeling in a thickness direction, thereby obtaining honeycomb structures wherein micro-pillars or anisotropic micro-pillars are regularly formed and arranged by said bisection on the peeled sections. The resulting structure, because of having a unique microstructure on its surface, possesses unique surface properties as compared with a film-like structure free of any microstructure or a structure with irregular pillars. Such unique properties could produce striking advantages inclusive of prominent touch. The inventive micro-pillar structure is expected to have applications in limitless technical fields, making a great deal of contribution to developments in the industry.

A process for producing a carbon structural body is provided, with which a carbon structural body having any of various nanostructures can be produced inexpensively and efficiently. The method includes forming a carbon-containing material into a pattern, coating the obtained pattern with a proto-shaped mold, and calcining and carbonizing the coated pattern.
摘要:
To provide an anisotropic conductive film which can respond to increasing pitch reduction of connection targets while maintaining connection reliability, and can be manufactured at a lower cost than conventional, and to provide a method of manufacturing the same. The anisotropic conductive film is provided with a porous film consisting of polymer, having numerous holes penetrating in a film thickness direction, the holes being in a honeycomb arrangement and having inner wall surfaces which curve outwards, a conductive material that fills the holes in the porous film, and an adhesive layer coated on both surfaces of the porous film. The porous film is formed by leaving a supporting substrate on which cast is a polymer solution where a polymer is dissolved in a hydrophobic, volatile organic solvent, under high humidity conditions.

Disclosed is a novel cell chip having a living cell retained on a substrate while keeping the functions of the cell. Specifically, disclosed is a cell chip which comprises a honeycomb-like porous material having through-pores therein and composed of a water-insoluble polymer and a human hepatocyte retained on the porous material. The cell chip, particularly one having a human hepatocyte retained on both surfaces of the honeycomb-like porous material, is advantageous, because it can keep the activity of a drug-metabolizing enzyme (particularly, a P450 activity) for a long period, can keep the number of the cells stably, and so on.
