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.

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.
