Abstract

The invention pertains to a method for manufacturing an antistatic aramid material selected from pulp, shortcut, fibrid, and fibril, comprising the steps of providing an aqueous medium comprising said aramid material, polymerizable monomer of a conductive polymer, anionic surfactant in an amount of at least 0.1 mole of anionic surfactant per kg aramid material (dry weight), and dopant in an amount of at least 0.1 mole per mole of monomer, adding an oxidizing agent to the medium to polymerise the monomer to form a polymer, and separating the aramid material provided with a polymer coating from the medium. The invention also pertains to an antistatic aramid material selected from pulp, shortcut, fibril, and fibrid, wherein the pulp, fibrid or fibril has a coating comprising a mixture of a conductive polymer and a dopant, and optionally at least 0.01 wt.% of an anionic surfactant. The antistatic aramid material according to the invention is suitable for use in, e.g., the 1 manufacture of paper, brake pads, and gaskets.
