  • Publication number: 20140349797
    Abstract: Disclosed herein is a method of manufacturing an endless belt, including the steps of: reacting a diamine monomer with a dianhydride monomer in a reactor filled with a conductive filler-dispersed liquid to obtain a reaction product, aging the reaction product and then discharging the aged reaction product from the reactor to prepare a semiconductive polyamic acid solution having a molecular weight distribution (Mw/Mn) of 1.3˜3.0 and a weight average molecular weight (Mw) of 30,000˜300,000; and applying the semiconductive polyamic acid solution to a seamless mold and completing an imidization reaction to obtain a polyimide film.

  • Patent number: 8288506
    Abstract: Disclosed is a method of manufacturing a conductive coating film having superior chemical resistance or solvent resistance and durability by chemically bonding a resin having an amine group (—NH2) with carbon nanotubes having a carboxyl group (—COOH). The conductive material having high bondability with carbon nanotubes and superior electrical properties includes carbon nanotubes uniformly contained therein, and thus has appropriate surface resistivity, and thereby can be used for antistatic, electrostatic dissipation and electromagnetic shielding purposes and in transparent or opaque electrodes depending on the resistivity value.
