Abstract EN
This paper aims to fabricate microhole arrays onto a silica glass via a room temperature imprint and subsequent sintering by using a monolithic SiO2-poly(vinyl alcohol) (PVA) nanocomposite as the silica glass precursor.
The SiO2-PVA suspension was prepared from fumed silica particles and PVA, followed by drying to obtain tailored SiO2-PVA nanocomposites.
The dependence of particle size of the fumed silica particles on pore size of the nanocomposite was examined.
Nanocomposites prepared from 7 nm silica particles possessed suitable mesopores, whereas the corresponding nanocomposites prepared from 30 nm silica particles hardly possessed mesopores.
The pore size of the nanocomposites increased as a function of decreasing pH of the SiO2-PVA suspension.
As a consequence, the crack-free monolithic SiO2-PVA nanocomposite was obtained using 7 nm silica particles via the suspension at pH 3.
Micropatterns were imprinted on the monolithic SiO2-PVA nanocomposite at room temperature.
The imprinted nanocomposite was sintered to a transparent silica glass at 1200°C in air.
The fabricated sintered glass possessed the microhole array on their surface with aspect ratios identical to the mold.
