摘要： Provided is an organic light-emitting display apparatus including a hybrid protective film. The organic light-emitting display apparatus includes a substrate, a display unit disposed on the substrate and including an organic light-emitting device (OLED), and an encapsulation unit encapsulating the display unit and including the hybrid protective film. The hybrid protective film includes an inorganic part layer where carbon is removed, an organic part layer where carbon is contained in a predetermined amount, and a gradient part layer disposed between the inorganic part layer and the organic part layer and increasing an amount of carbon as being more contiguous to the organic part layer.

摘要： Disclosed are a method and an apparatus for preparing an alkylene carbonate using a polyamine-based heterogeneous catalyst. The rapid increase in reactor temperature and the risk of explosion due to heat of reaction may be prevented by recycling the produced alkylene carbonate to the reactor. Accordingly, it is possible to obtain the alkylene carbonate stably and continuously with high yield while maintaining reaction temperature and pressure constant.

摘要： Disclosed are a carbon dioxide absorbent composition in which an N-alkylaminoalkanol; a polyhydroxyamine-based compound; and ethylenediamine and/or diethylenetriamine are mixed, a method for preparing the same, and a method and an apparatus for carbon dioxide absorption/separation using the same. Since the carbon dioxide absorbent according to the present disclosure has superior carbon dioxide absorption capacity and remarkably lower absorbent recycling temperature as compared to the existing absorbents such as monoethanolamine, etc., total energy consumption in the capturing process can be reduced greatly. In addition, since carbon dioxide is recovered at low recycling temperature, contamination by water or absorbent vapor may be prevented.
