    摘要: This invention provides a porous glass with a varied porous structure that shows an excellent optical performance. A method of manufacturing a porous glass comprising: a first step of forming a surface layer containing a boron compound and an alkali metal compound as main ingredients on a matrix glass containing a silicon oxide, a boron oxide and an alkali metal oxide; a second step of heat treatment the matrix glass and the surface layer for phase separation to form a phase-separated glass; and a third step of acid treatment the phase-separated glass to form the porous glass having pores.

    摘要: Provided is a method of producing a porous glass, including selectively etching a phase-separated glass with an acid solution, in which the method allows a processing time to be shortened and suppresses gel-like silica from remaining and being deposited in pores of a porous portion. The method of producing a porous glass includes: immersing the phase-separated glass in a bath containing an acid solution; setting an angle θ, which is formed by a surface to be porosified of the phase-separated glass and a bath liquid surface, to 10° or more to 90° or less; and irradiating the bath with an ultrasonic wave to etch the phase-separated glass, thereby obtaining the porous glass.

    摘要: A composite material is constituted by fine nano-oxide particles, a dispersant, and a transparent resin material. The dispersant includes a polymer of vinyl monomer having a binding acidic group. When φ is a dimensionless number defined by an average particle size (nm) of the fine nano-oxide particles divided by nm, the polymer has a degree of polymerization of an integer of 3 or more and 8×φ or less with the proviso that the integer is a numerical value obtained by dropping a decimal fraction. The composite material is produced through a step of obtaining a dispersant comprising a polymer by polymerizing a vinyl monomer having a binding acidic group in the presence of polyamine or in an aqueous dilute dispersion, and a step of mixing the dispersant, fine nano-oxide particles, and a transparent resin material.
