摘要

PROBLEM TO BE SOLVED: To provide fine mesoporous silica particles which are capable of a good balance between functions such as low reflectance (Low-n), low dielectric constant (Low-k) and low thermal conductivity, and high strength of a molded article.;SOLUTION: The fine mesoporous silica particles are produced by a process that comprises a step of preparing surfactant composite fine silica particles and a step of making the surfactant composite fine silica particles into fine mesoporous silica particles. In the fine silica particle preparation step, a surfactant, water, an alkali, a hydrophobic portion-containing additive that comprises a hydrophobic portion for increasing the volumes of micelles, and a silica source are mixed, thereby preparing the surfactant composite fine silica particles. In the mesoporous particle formation step, the surfactant composite fine silica particles are mixed with an acid and an organosilicon compound, thereby removing the surfactant and the hydrophobic portion-containing additive contained in the surfactant composite fine silica particles and providing the surface of each fine silica particle with an organic functional group. Each fine mesoporous silica particle comprises mesopores in the inner portion, and is modified with the organic functional group at the surface.;COPYRIGHT: (C)2011,JPO&INPIT
