    • A porous clay composite having fine metal particles deposited substantially only on surfaces of inorganic particles which are intercalated between layers of an expandable clay is obtained. After the expandable clay is expanded with a solvent into an expanded clay, the inorganic particles are intercalated between the layers of the expanded clay. The inorganic particles have photo-semiconducting property, that is, a plurality of carriers such as electrons and holes are released from the inorganic particles by irradiation of a light such as ultraviolet light. A solution including metal ions is mixed with the inorganic particles intercalated clay to form a mixed solution thereof. Subsequently, the light is irradiated to the mixed solution to deposit the fine metal particles substantially only on the inorganic particles which are intercalated between the layers of the expanded clay, so that the porous clay composite is formed in the mixed solution. The porous clay composite including the mixed solution is dried by a supercritical drying or a carbon dioxide extractive drying, etc., so as not to disrupt a porous structure thereof. When a metal having oxidation/reduction catalysis is used as the fine metal particles, the porous clay composite functions as an excellent oxidation/reduction catalyst.
    • 获得了一种多孔粘土复合材料,其具有基本上仅沉积在可膨胀粘土层之间的无机颗粒表面上沉积的金属微粒。 将可膨胀粘土用溶剂膨胀成膨胀粘土后,将无机颗粒插入膨胀粘土层之间。 无机粒子具有光半导体性质,即,诸如电子和空穴的多个载流子通过照射诸如紫外光的光从无机颗粒释放。 将包含金属离子的溶液与无机颗粒插入粘土混合以形成其混合溶液。 随后,将光照射到混合溶液中,以将细金属颗粒基本上仅沉积在插入膨胀粘土层之间的无机颗粒上,从而在混合溶液中形成多孔粘土复合材料。 包含该混合溶液的多孔粘土复合物通过超临界干燥或二氧化碳萃取干燥等干燥,以免破坏其多孔结构。 当使用具有氧化/还原催化的金属作为金属微粒时,多孔粘土复合材料用作优异的氧化/还原催化剂。

    • A hydrophobic aerogel is fabricated by reacting a polymer having a skeleton structure of (SiO.sub.2).sub.n with a hydrophobic agent having hydrophobic groups as well as functional groups reactive to silanol groups to obtain a denatured polymer, forming a gel consisting of two phase of a dispersing medium and the denatured polymer which was performed a hydrophobic treatment, and then, supercritically drying the gel at temperature and pressure above a critical point of the dispersing medium. The hydrophobic aerogel has improved characteristics free from deterioration in light transmissivity as well as lowered thermal resistance and also free from a dimensional variation such as shrinkage which would otherwise occur by contact with moisture, so that it can maintain the excellent characteristics for long time periods. Particularly, the aerogel is useful as a material having excellent light transmissivity and thermal resistance.
    • 通过使具有(SiO 2)n的骨架结构的聚合物与具有疏水基团的疏水剂以及与硅烷醇基反应的官能团反应来制备疏水性气凝胶,以获得变性聚合物,形成由两相分散体 介质和进行疏水处理的变性聚合物,然后在高于分散介质的临界点的温度和压力下超临界干燥凝胶。 疏水性气凝胶具有改善的光透过性劣化特性以及耐热性降低的特征,并且也不受诸如通过与水分接触而产生的收缩等尺寸变化的影响,从而能够长期保持优异的特性。 特别地,气凝胶作为具有优异的透光性和耐热性的材料是有用的。
