摘要： A flexible electronic device containing a polyimide film exhibiting excellent C-V characteristics. The polyimide film is a film that shows a maximum gradient of 0.005N or more in a capacitance-voltage measurement of a laminate in which a polyimide film having a film thickness of 0.75 μm is formed on a silicon wafer having a resistance value of 4 Ωcm; the maximum gradient meaning a maximum value of an absolute value of a gradient in a normalized capacity-voltage curve during a third scan of forward direction scans; a capacity-voltage curve being measured by applying a direct current voltage is to the polyimide film with respect to the silicon wafer between a lowest voltage V1 and a highest voltage V2, and measuring capacitance while the direct current voltage is scanned in a forward direction and scanned in a negative direction; the normalized capacity-voltage curve is being normalized so that the capacity at the lowest voltage V1 is 1.

摘要： Disclosed is a method for producing a polyimide laminate, the method including the steps of applying a polyimide precursor solution onto a substrate and heating the polyimide precursor solution, to thereby form a polyimide film layer on the substrate. The substrate is any plate selected from a glass plate, a metal plate, and a ceramic plate. The heating step includes irradiation with far infrared rays using an infrared heater that generates a maximum radiant energy at an infrared wavelength of 3.5 to 6 μm. The highest heating temperature is preferably 350 to 550° C. The time required to increase the temperature from 180 to 280° C. during a temperature-increasing process is preferably 2 minutes or longer.

摘要： In an embodiment, a film retainer 200 includes a base member 210 fixed to a tenter chain and a pin plate 220 supported on the base member 210 to be movable in the movement direction of the tenter chain. The pin plate 220 is provided with a plurality of protruding pins 230 that are stuck into the film for holding the film. The film retainer for a tenter apparatus is capable of suppressing a bowing phenomenon without significant modifications to an existing manufacture facility and being applicable under arbitrary manufacture conditions.
