Abstract: An optical inspection apparatus includes a broadband light source, a monochromator, an image obtaining apparatus, and an analysis device. The monochromator is configured to convert light from the broadband light source into a plurality of monochromatic beams of different wavelengths and sequentially output the monochromatic beams, where each beam has a preset wavelength width and corresponds to one of a plurality of different wavelength regions. The image obtaining apparatus is configured to allow each monochromatic beam output from the monochromator to be incident to a top surface of an inspection target without using a beam splitter, allow light reflected by the inspection target to travel in a form of light of an infinite light source, and generate 2D images of the inspection target. The analysis device is configured to analyze the 2D images of the inspection target in the plurality of wavelength regions.

Abstract: The present invention relates to a high strength organic/inorganic composite using plate-shaped inorganic particles and to a method for preparing the same. The organic/inorganic composite of the present invention comprises a polymer and inorganic particles uniformly arranged into a matrix structure in said polymer. A mineral bridge is formed between the inorganic particles. According to the present invention, plate-shaped inorganic particles are uniformly distributed in the polymer to improve the filling rate of inorganic particles, and a mineral bridge is formed between the inorganic particles to provide a high strength and lightweight organic/inorganic composite. The organic/inorganic composite of the present invention may be widely used in high value-added industry such as an aerospace industry, space industry, car industry, energy industry, environmental industry, defense industry and construction industry.

Abstract: Provided are polycarbosilane and a method of producing the same. The polycarbosilane contains an allyl group, and thus can be cured by UV absorption when not exposed to the air.

Abstract: The present invention is related to a method of producing polycarbosilane by heating polydimethylsilane at low pressure within the range of 320˜450° C. using zeolite having the Si/Al or Si/B ratio of 1˜200 as catalyst. This invention uses a zeolite with the structure of ZSM-5, ZSM-11, ZSM-12, zeolite X and zeolite Y, which has the Si/Al or Si/B ratio of 1˜200, as catalyst. When polycarbosilane is produced using a specific zeolite as catalyst, Si/Al or Si/B ratio can be adjusted at any proportion, enabling acidity control of catalyst, and therefore the molecular weight of final products can be easily controlled and the product yield can be improved, compared to conventional solid acid catalysts.
