A method capable of easily producing a nanostructured material having regular nanoscale arrangement. The method comprises a raw material solution preparation step of preparing a raw material solution by dissolving, in a solvent, a block copolymer comprising a polymer block component “A” and a polymer block component “B” which are immiscible to each other, and an inorganic precursor which coordinates with the polymer block component “A” but does not coordinate with the polymer block component “B”; and a nanostructure-forming step of forming a nanophase-separated structure “10” in which a polymer phase “1A” comprising the polymer block component “A” with which the inorganic precursor is coordinated, and a polymer phase “1B” comprising the polymer block component “B” are regularly arranged by self-assembly. A nanostructured material can be obtained by this method. Moreover, by converting the inorganic precursor to an inorganic component, it is possible to obtain an organic/inorganic nanostructured material “20” comprising a polymer phase “2A” containing the inorganic component and a polymer phase “1B”. Furthermore, by removing the organic component, it is also possible to obtain an inorganic nanostructured material “30”.

Porous materials having a metal oxide skeleton are taught that have various water vapor adsorption capacities defined by the amount of adsorbed water vapor at a specific relative vapor pressure in a water vapor adsorption isotherm. A preferred porous material has a water vapor adsorption capacity that is less than or equal to 0.1 g/g at a relative vapor pressure of 10%, and greater than or equal to 0.2 g/g at a relative vapor pressure of 28%. Methods of making such porous materials are also taught. A preferred method for forming a porous material includes condensing a skeleton starting material for the porous material, in the presence of a surfactant, in a solution which has a concentration of the skeleton starting material in the solution that is less than or equal to 0.4 mol/L and a molar ratio of the surfactant to the skeleton starting material that is greater than or equal to 0.05 and less than or equal to 50, to form a condensate and removing the surfactant from the condensate.

This invention provides liquid crystal compositions for light controlling materials of light scattering type having both memory and high speed response characteristics. The composition neither needs a temperature controlling device nor a device for imparting a shear stress as a memory erasing device, because the composition comprises a two-frequency addressing liquid crystal or such liquid crystal with an ionic component. The two-frequency addressing liquid crystal responds to an electric field and exhibits a positive dielectric anisotropy or a negative dielectric anisotropy depending on the frequency region of the electric field. Because the flat shaped particles of the present invention exhibit an affinity with the liquid crystal, the particles are dispersed in the liquid crystal and form liquid crystal domains effectively.
摘要:
A process for producing a water glass-based material and the inorganic material itself is disclosed. The process involves providing an amount of water glass and causing a solid content of the water glass to react with a coagulant. The reaction is created in one of three possible general ways. Firstly, the water glass and coagulant can be reacted by heating the mixture to a temperature in the range of 80.degree. C. to 600.degree. C. Secondary, the water glass and coagulant can be reacted by providing an alkaline substance in combination with them. Thirdly, the water glass and coagulant can be reacted by providing the coagulant in the form of porous particles which include polyvalent ions capable of coagulating the water glass. All three methods of reacting the coagulant and water glass can include one or more heating steps. The material produced is particularly resistant to heat, water and the combination of heat and water. The material provides a strong adhesive and can be utilized to shape molded objects since it remains in a moldable state for a long period of time after the components are mixed together.
