The invention discloses a functional slurry used for chip-type polymer electro static discharge suppressors. The functional slurry used for chip-type polymer electro static discharge suppressors comprises, by weight, 30 to 40 parts of an organic carrier, 20 to 30 parts of a conductive material, 10 to 20 parts of a semi-conductive material, 5 to 10 parts of barium sulfate, 1 to 5 parts of glass bead, and 1 to 5 parts of a dispersant. The functional slurry is capable of preventing material electric leakage caused by metal mutual contaction, preventing increasing of working voltage caused by oxidation of the conductive material in production process, adjusting surface coating layer thickness, adjusting electrostatic trigger voltage, and improving product stability.
