Publication number: 20200326604Abstract: A transmittance-variable film, a use thereof, and a smart window including the same are disclosed herein. In some embodiments, a transmittance-variable film includes a first electrode substrate, a first electrode insulating layer disposed on the first electrode substrate, an electrophoretic layer, a second electrode insulating layer, and a second electrode insulating layer disposed on the second electrode substrate, wherein the first electrode substrate, the electrophoretic layer, and the second electrode substrate are sequentially arranged, and wherein the first and second electrode insulating layers contain a fluorine-based resin. Upon repeated driving of the film between a transparent mode and a black mode, the transmittance-variable film can maintain a transmittance constant in the transparent mode and exhibit an excellent light shielding ratio in the black mode.Type: ApplicationFiled: November 2, 2018Publication date: October 15, 2020Applicant: LG Chem, Ltd.Inventors: Young Sik Yoon, Tae Gyun Kwon, Moon Soo Park

Publication number: 20190291385Abstract: The present application relates to a conductive film and a method for preparing the same. The conductive film comprises a continuous phase; and a plurality of separate phases formed in the continuous phase. The continuous phase comprises a polymer, and the separate phase comprises conductive particles. The separate phase is distinguished from the continuous phase by an amphipathic compound. The present application can simplify the production process and reduce the production cost because drivable particles can be trapped without being subjected to a separate barrier forming process.Type: ApplicationFiled: October 30, 2017Publication date: September 26, 2019Inventors: Tae Gyun KWON, Young Sik YOON, Moon Soo PARK
