▎ 摘 要
NOVELTY - Capacitor (200) comprises first electrode, second electrode and a polypropylene composite material located between the first electrode and the second electrode, where the polypropylene composite material includes a filler and a matrix material. The base material is 500-800 pts. wt. polypropylene resin, and the filler includes 100-200 pts. wt. ruthenium dioxide, 80-120 pts. wt. calcium carbonate, and 40-60 pts. wt. carbon fiber. USE - Capacitor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of capacitor. Capacitor (200) Metal foils (201) Film (202, 204) Polypropylene film (203)
