    • A process for producing superhydrophobic powders comprising silica as the main component and the surface of the powders have a contact angle with water of 150° or larger; and a structure having a superhydrophobic surface comprising the powders. The process comprised: introducing hydrophobic groups into the silica present in the surface of aggregates of organic/inorganic composite nanofibers obtained by combining a polymer, which is an organic substance, with silica, which is an inorganic substance, on the order of nanometer or into the silica obtained by calcining the organic/inorganic composite nanofibers and removing the polymer there from; and thereby making powders composed of the aggregates superhydrophobic. Also provided is a superhydrophobic powders obtained by the process. The structure having a superhydrophobic surface is obtained by fixing the superhydrophobic powders to a surface of a solid substrate.
    • 以二氧化硅为主要成分的超疏水性粉末的制造方法,粉末的表面与水的接触角为150°以上; 以及具有包含粉末的超疏水表面的结构。 该方法包括:将存在于有机/无机复合纳米纤维的聚集体表面的二氧化硅引入到二氧化硅中,该有机/无机复合纳米纤维通过将作为有机物质的聚合物与作为无机物质的二氧化硅组合而成, 通过煅烧有机/无机复合纳米纤维并从其中除去聚合物获得的二氧化硅; 从而制成由聚集体组成的超疏水性粉末。 还提供了通过该方法获得的超疏水性粉末。 通过将超疏水性粉末固定在固体基材的表面上,获得具有超疏水性表面的结构。

    • A styrene resin composition is provided which has a high molecular weight enabling a molded product obtained therefrom to have satisfactory strength, has a high melt mass-flow rate, high melt tension, and hence excellent moldability, and is less apt to gel during production, and a process for producing such a styrene resin composition. The styrene resin composition comprises a linear polystyrene having a weight average molecular weight of 200,000 to 350,000 and a multibranched polystyrene having a weight average molecular weight of 1,000,000 to 10,000,000, has an average molecular weight of 250,000 to 700,000, and a melt mass-flow rate (MFR) and melt tension (MT) which satisfy the following formulas (1) and (2) respectively: MFR≧45×exp(−0.1×Mw×10−4)  (1) MT≧0.07Mw×10−4+1.8  (2).
