Tungsten-containing Mesoporous Silica Thin Film, Highly Hydrophilic Material Containing the Same, and Method for Producing Tungsten-Containing Mesoporous Silica Thin Film

摘要

A tungsten-containing mesoporous silica thin film, which is a mesoporous silica thin film formed from a solution containing a silica precursor and a water-soluble tungsten compound, and has a molar ratio (W/Si) of tungsten content to silicon content of 0.001 to 0.04, a film thickness of 0.1 to 5 μm, and an average pore diameter of 20 nm or less.
