  • Patent number: 10472276
    Abstract: A composition for forming film having wrinkle structure and a method of forming the film are disclosed. The composition includes photo-curable agent and photoinitiator dissolved in the photo-curable agent. The cut off wavelength of light transmittance of the photo-curable agent is greater than the cut off wavelength of light absorbance of the photoinitiator. Photo-cured thin film is formed at the upper portion of composition layer at an initial time period of irradiation. By subsequent contraction, the photo-cured thin film forms wrinkles. The wrinkle structure is controlled by the relation of the cut off wavelength of light transmittance of the photo-curable agent and the cut off wavelength of light absorbance of the photoinitiator, the photo-curing rate of the composition and the thickness of the composition layer, and the photoinitiator concentration, etc., before photo-curing. The film may increase the emission efficiency of LED and OLED and the sensing effect of sensor.

  • Publication number: 20190126212
    Abstract: The present disclosure relates to a technique for manufacturing a self-humidifying membrane including a hydrophobic thin film-coating layer having a nano-sized crack morphology pattern on the surface of an aromatic hydrocarbon-based polymer ion exchange membrane and applying the membrane to a reverse electrodialysis process. The self-humidifying membrane including a hydrophobic thin film-coating layer having a nano-sized crack morphology pattern on the surface of an aromatic hydrocarbon-based polymer ion exchange membrane, manufactured according to the present disclosure, embodies a low bulk resistance of the ion exchange membrane and significantly improves ion selectivity, thereby overcoming the trade-off relationship between membrane resistance and ion selectivity, and thus may be commercially available as an anion and cation exchange membrane of a reverse electrodialysis device.
