International. Japanese scientists successfully fabricated a cured organic-inorganic composite material in which squamous silica was well dispersed, with a tetrafunctional epoxy resin and chemically modified squamous silica through an effective anionic UV curing system using base proliferation reactions.
Chemically modified squamous silica (SS) was prepared with base amplifier groups (1.4% by weight vs. SS), and anionic UV curing of an epoxy resin containing 100% by weight of chemically modified SS was achieved after 5000 mJ/cm2 of light irradiation at a wavelength of 365 nm and subsequent heating to 160 °C for 30 min.
It was found by a scanning electron microscopy study that the chemically modified SS was well dispersed in the UV-cured film and that unmodified SS was found to be added.
