Abstract:
PURPOSE: Cloth for automobile interior materials with an EL light emitting layer is provided to improve visibility of the cloth with a sensitive light in a vehicle through indirect illumination by an organic EL, and to improve interiors of the vehicle. CONSTITUTION: Cloth for automobile interior materials with an EL light emitting layer comprises the following: an EL light emitting layer(111); a transparent protective layer(112) located on the top of the EL light emitting layer; and an insulating layer(113) insulating the EL light emitting layer from the external side, and located on the bottom of the EL light emitting layer. The EL light emitting layer is weaved with a warp and a weft threads. The weft threads are made with EL strips. The warp threads are made with slit yarns.
Abstract:
A multi-porous separation film for a secondary battery is provided to ensure excellent thermal stability and tensile strength and to impart high output due to excellent impregnation property to the electrolyte. A manufacturing method of a multi-porous separation film for a secondary battery with high power output and thermal stability comprises (a) a non-solvent addition step for adding a non-solvent to a poly [(vinylidene fluoride)-co-(hexafluoropropylene)] (PVDF-HFP) and heat-dispersing an additive at 35~45 °C, (b) an inorganic additive addition step for adding SiO2 or Al2O3 as a inorganic additive to the product of the step (a) and heat-dispersing the additive at 35~45 to obtain a coating composition in a slurry form, (c) a coating step for bar-coating one side or both sides of the film with a coating composition of a slurry form with a thickness of 60-90 micron, and (d) a washing and drying step for coagulating the coated porous separation film with water at 20~30 °C, washing the coagulated separation film with an alcohol, and drying the washed separation film in a drying oven of 65~75 °C. The non-solvent is selected from the group consisting of ethanol, 1- propanol, 2- butanol, isobutanol, 3- pentanol, dodecanol, N-methyl-2-pyrrolidinone(NMP) and dimethylformamide(DMF).
