Document Type and Number:
WIPO Patent Application WO/2020/184438
Kind Code:
A1
Abstract:
Provided are: a liquid composition from which a ferroelectric insulation sheet can be produced that has excellent flexibility, dielectric properties including a high dielectric constant and a low dielectric loss tangent, and bondability or adhesiveness; a method for producing a ferroelectric insulation sheet using said liquid composition; and a ferroelectric insulation sheet having excellent flexibility, the above-mentioned dielectric properties, and adhesiveness or bondability. A liquid composition according to the present invention comprises: powder including a tetrafluoroethylene-based polymer having a melt viscosity of 1×102-1×106 Pa·s at 380°C, and having an average particle diameter of 30 μm or less; an inorganic filler having a dielectric constant of 10 or more at 25°C; and a liquid dispersion medium, wherein the liquid composition has a viscosity of 50-10,000 mPa·s at 25°C.
