    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 0.005/V 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 being normalized so that the capacity at the lowest voltage V1 is 1.

    摘要: Provided is a laminate that has excellent low-temperature impact resistance and bursting pressure strength at high temperatures despite having a thick modified polyolefin layer. The laminate has two or more layers including an (a) layer and a (b) layer, the (a) layer includes an aliphatic polyamide composition (A), and the (b) layer includes a modified polyolefin (B). The modified polyolefin (B) includes a unit derived from a monomer based on an α-olefin having 2-10 carbon atoms, and a unit derived from an unsaturated compound having at least one functional group selected from the group consisting of: unsaturated compounds having at least one group selected from the group consisting of a carboxyl group, a hydroxyl group, an epoxy group, an amino group, an amide group, an imide group, a nitrile group, a thiol group, and an isocyanate group; and derivatives of unsaturated compounds having a carboxyl group. The Shore hardness (D scale) of the modified polyolefin (B) as measured according to ASTM D2240 is 30-61.

    摘要: A biomass solid fuel with reduced self-heating. An apparatus for manufacturing a biomass solid fuel including a carbonization furnace for carbonizing a biomass molded block to obtain a biomass solid fuel; a yield calculator for calculating a yield of the biomass solid fuel and/or a temperature detector for measuring a temperature of the carbonization furnace; and a controller for controlling a heat source of the carbonization furnace; in which the controller controls the heat source based on a correlation between (i) a self-heating property of the biomass solid fuel and (ii) the yield and/or the temperature of the carbonization furnace.
