A polyimide film formed using the polyimide precursor composition has improved heat resistance and mechanical properties, and has high absorbance in a wavelength range in an ultraviolet region.

Abstract: The present invention provides a water electrolysis electrode including a catalyst having a three-dimensional nanosheet structure with a low overvoltage and excellent catalytic activity, a method for producing the same, and a water electrolysis device including the same. The water electrolysis electrode according to the present invention includes a catalyst layer, which includes a composite metal oxide and has a three-dimensional nanosheet structure, and an electrode substrate. The method for producing a water electrolysis electrode according to the present invention comprises steps of: immersing an electrode substrate in an electrolyte solution containing metal oxide precursors; electrodepositing composite metal hydroxides by applying a voltage to the electrode substrate; and forming a composite metal oxide by annealing the electrode substrate. The water electrolysis device according to the present invention includes the water electrolysis electrode according to the present invention as an anode.

Abstract: The present invention relates to a planar heating sheet, including a linear heating member including a single fiber body and a plurality of heating wires surrounding the single fiber body, wherein the heating wire includes a metal wire, an organic compound layer applied on the metal wire, and a metal oxide layer applied on the organic compound layer. Since the planar heating sheet is realized by a plurality of linear heating members each formed by coating a single fiber body with heating wires, each including a metal nanowire, an organic compound layer applied on the metal nanowire, and a metal oxide layer applied on the organic compound layer, this planar heating sheet can be naturally folded or bent like a general woven fabric, and thus can be used in a wide range.

Abstract: The object of the present device is to provide a fixing clip for a pipe wherein the pipe can be inserted into and fixed at the clip which is constituted into one structure and a shelf can be combined to the fixed clip so that articles can be positioned or decorated on the shelf. To achieve the above object, the present device comprises a first body formed with a first hole into which the pipe is inserted; a second body formed with a second hole into which the pipe is inserted; a connection section which combines ends of the first body and the second body and elastically presses the other ends of the first body and the second body so as to be pushed away from each other; and a fixing section to which the other end of the first body or the second body is connected, wherein the first body and the second body can be fixed at or escape from the pipe according to the angle between the center axis of the first hole and the center axis of the second hole.
