The present invention relates to a method for preparing nanoporous carbons with enhanced mechanical strength and the nanoporous carbons prepared by the method, and more specifically, to a method for preparing a nanoporous carbon, comprising the steps of (i) synthesizing a mesoporous silica template not being subjected to any calcination process; (ii) incorporating a mixture of a monomer for addition polymerization and initiator, or a mixture of a monomer for condensation polymerization and acid catalyst into the as-synthesized mesoporous silica template, and reacting the mixture to obtain a polymer-silica composite; and (iii) carbonizing the polymer-silica composite at a high temperature to obtain a carbon-silica composite, from which the silica template is then removed using a solvent. According to the preparation method of the present invention, the nanoporous carbons having uniform size of mesopores, high surface area and high mechanical stability can be prepared at low preparation cost through a simplified preparation process. Therefore, the nanoporous carbons of the present invention can be used as catalysts, catalyst supports, separating agents, hydrogen reserving materials, adsorbents, membranes and membrane fillers in various application fields.

The present invention provides a composition for preparing porous dielectric thin films containing pore-generating material, said composition comprising gemini detergent, and/or a quaternary alkyl ammonium salt, a thermo-stable organic or inorganic matrix precursor, and solvent for dissolving the two solid components. There is also provided an interlayer insulating film having good mechanical properties such as hardness, modulus and hydroscopicity, which is required for semiconductor devices.

Composition for preparing porous dielectric thin films

Disclosed herein are a novel gemini surfactant and a method for preparing a mesoporous material using the gemini surfactant. The method for preparing a mesoporous material uses the novel gemini surfactant as a structure-directing agent to provide a mesoporous material has a pore size of 10 nm or less with uniform pore size distribution.

A rapid and efficient process of forming a metal-containing pattern by producing, through photoreaction, a difference in solubility between exposed and unexposed areas of a thing film, and developing the film to produce a patterned film, followed by oxidation or reduction to provide a pure metal or metal oxide pattern.

Process of forming a micro-pattern of a metal or a metal oxide

An organic metal precursors containing one or more organic ligands bonded to one or more metal atoms, wherein the organic ligand is rapidly dissociated from the metal atom upon exposure to light and degraded leaving a metal or a metal oxide. By using the organic metal precursors, an electroconductive, metal-containing patterned film can be easily deposited on a substrate at room temperature under atmospheric pressure without using photosensitive resins.

Organic metal precursor for use in forming metal containing patterned films

Disclosed are a metallic nanoparticle cluster ink and a method for forming a conductive metal pattern using the cluster ink. The metallic nanoparticle cluster ink comprises colloidal metallic nanoparticles and a bifunctional compound. The conductive metal pattern is formed by forming a metallic nanoparticle pattern on a substrate using a mold made from PDMS (poly(dimethylsiloxane) polymer as a stamp, and heat-treating the substrate. Micrometer-sized conductive metal patterns can be easily formed on various substrates in a simple and inexpensive manner without the use of costly systems, thereby being very useful in various industrial fields.
