Abstract:
Provided is a photo-curable transparent resin in which an oxetane monomer for promotion of photo-curing, control of viscosity, and improvement of physical properties is mixed with a photo-cationically polymerizable cyclo-aliphatic epoxy group-containing oligosiloxane resin prepared by a sol-gel reaction. The photo-cationically polymerizable photo-curable transparent resin added with the oxetane monomer provides a cured product having high curing density and retaining excellent mechanical properties, thermal-mechanical properties, and electrical properties.
Abstract:
Provided is a non-hydrolytic transparent composite composition having excellent transparency and heat resistance, and a low thermal expansion coefficient. Particularly, the transparent composite composition includes a glass filler dispersed in a crosslinked transparent resin produced by a non-hydrolytic reaction. The non-hydrolytic transparent siloxane resin is a resin having Si—O (siloxane) bonds, a resin having at least one kind of heterometal bonds, including Si—O bonds, or the resin further containing other ingredients. When the transparent siloxane resin produced by a non-hydrolytic reaction forms a composite in combination with the glass filler, the composite realizes high transparency and heat resistance, as well as a low thermal expansion coefficient. Therefore, the transparent composite composition is useful as a substrate for thin film transistor (TFT) devices, display devices and optical devices.

The present invention provides a fluorescent dye-silane hybrid resin manufactured by polycondensing an alkoxysilane bonded with a fluorescent dye with an organo-silane. More particularly, the present invention provides a fluorescent dye-siloxane hybrid resin that is manufactured by reacting a fluorescent dye having one or more functional groups with an alkoxysilane having an organic functional group to form an alkoxysilane bonded with the fluorescent dye and then polycondensing the alkoxysilane bonded with a fluorescent dye with an organo-silanediol and an organo-alkoxysilane having a thermocurable or ultraviolet-curable functional group without water. The fluorescent dye-silane hybrid resin has excellent thermostability, photostability, fluorescence characteristics, and processibility.

Disclosed is a method of fabricating a flexible device, which includes surface-treating one or both sides of a carrier plate so that regions with different surface-treatments are formed on the same side of the carrier plate, forming a glass-filler reinforced plastic substrate film on the surface-treated carrier plate, forming thin film patterns on the glass-filler reinforced plastic substrate film, and separating the glass-filler reinforced plastic substrate film having the thin film patterns formed thereon from the carrier plate, and in which the surface-treating of the carrier plate enables the glass-filler reinforced plastic substrate film to be easily separated from the carrier plate without an additional process such as using a solvent or a laser release technique.

Abstract:
Disclosed is a method of producing a planar multimode optical waveguide by direct photo-patterning and, more particularly, to an optical waveguide material and a method of producing the same. It is possible to control the refractive index of the optical waveguide, and the optical waveguide has a desirable refractive index distribution throughout different dielectric regions. In the method, it is unnecessary to conduct processes of forming a clad layer and of etching a core layer, thus a production process is simplified. The method comprises coating a photosensitive hybrid material having a refractive index or a volume changed by light radiation, in a thickness of 10 microns or more, and radiating light having a predetermined wavelength onto the coated photosensitive hybrid material to form the multimode optical waveguide due to a change in refractive index of a portion onto which light is radiated.
