Abstract: The present invention relates to a coating composition having excellent wavelength conversion efficiency and a wavelength converting thin film/sheet prepared using the same. The coating composition of the present disclosure includes 1 to 60 wt % of polyorgano-silsesquioxane, 0.0001 to 30.0 wt % of a wavelength converting agent, and a solvent, and exhibits a transmittance of 70% or more as compared to that of an aqueous solution. A wavelength converting thin film/sheet prepared by using the coating composition has not only excellent photoluminescence, thermal resistance, and light-fastness, but also moisture and oxygen permeability is low, and the visible light transmittance thereof is 70% or more as compared to that of the air, and when patterning is added, the photoluminescence intensity of sheet is at least two-fold higher than that of a non-patterned sheet. Therefore, the coating composition of the present invention may be conveniently used in the preparation of a wavelength converting thin film/sheet, and feasibly applied to the preparation of a solar cell in an efficient manner.

Abstract: The present disclosure provides a gas separation membrane using a ladder-structured polysilsesquioxane in which organic functional groups are attached to a long siloxane chain and a method for fabricating the same. In accordance with the present disclosure, a free-standing ladder-structured polysilsesquioxane-based membrane with various functional groups can be fabricated for gas separations. The performance of the gas separation membrane can be controlled through a variety of combinations of the organic functional groups linked to the siloxane chain. In addition, by controlling the molecular structure of the gas separation membrane through mixing of the ladder-structured polysilsesquioxane with an amine compound or conventional glassy or rubbery polymers or through thermal/UV-curing, the permeability and selectivity of the gas separation membrane can be controlled selectively.

Abstract: Provided is a composition for use in fabricating a carbon molecular sieve membrane, including a fluorine-containing polymer matrix and polysilsesquioxane. The composition shows high selectivity to the gas to be separated and high separation quality by controlling the mixing ratio of the fluorine-containing polymer matrix with polysilsesquioxane as well as the type of fluorine-containing polymer matrix and polysilsesquioxane. Ancillary selective pore formation is enhanced by a so-called “autogenous fluorinated gas induced siloxane etching” (A-FISE) mechanism of fluorine-containing polymer/polysilsesquioxane blend precursors during carbonization. Therefore, it is possible to effectively separate gases having a small difference in particle size, which, otherwise, are difficult to be separated with the conventional polymer membranes.
