    • Provide a porous silica which can be easily formed into various shapes excellent transparency, capable to be nanoparticulated, capable to be obtained at a high efficiency even when a cationic surfactant having 7 or less carbon atoms is used. Alkoxysilane is dispersed with a cationic surfactant in which a hydrophobic moiety has 2 to 7 of carbon atoms, and added water of which pH is adjusted to 0-2 with the amount of 2-4 equivalents to the alkoxysilane, and mildly hydrolyzed to obtain a monolithic mesoporous silica of which a pore diameter is not less than 0.5 nm and less than 2 nm. Furthermore, a pore diameter can be slightly controlled by adding an organic silane to the system. By adding polyethylene glycol to the synthesis system, a monolithic mesoporous silica nanoparticle is obtained. A precursor solution prior to gelation is: (1) droped to a basic aqueous solution to obtain a mesoporous silica bead or the like; (2) spincoated on a substrate to obtain a thin film; or (3) sprayed with a spinner to obtain a fiber, respectively.

    • A blade rubber having both of superior durability and wiping performance can be manufactured by using a non-diene-based rubber without environmental burden. A pair of blade-rubber molded bodies molded from the non-diene-based rubber is subjected to an irradiation treatment to generate radical active sites, and monomers are bound by graft polymerization as beginning at the radical active sites. Also, the monomers are adhered on a surface of the blade rubber either before or after the generation of the radical active sites. The irradiation treatment and the graft polymerization may be simultaneously performed or independently performed in this order. In this manner, a surface treatment for reducing friction of the non-diene-based rubber having superior durability can be performed without halogen, and therefore, a blade rubber having superior durability and wiping performance can be manufactured.
    • 具有优异的耐久性和擦拭性能的刀片橡胶可以通过使用不带环境负荷的非二烯类橡胶来制造。 对由非二烯类橡胶成型的一对刀片橡胶成型体进行照射处理以产生自由基活性部位,并且通过接枝聚合将单体与基团活性部位开始接触。 此外,单体在产生基团活性部位之前或之后粘附在刮片橡胶的表面上。 照射处理和接枝聚合可以按顺序同时进行或独立地进行。 以这种方式,可以在没有卤素的情况下进行具有优异耐久性的非二烯类橡胶的摩擦降低的表面处理,因此,可以制造具有优异耐久性和擦拭性能的刮板橡胶。
