  • Publication number: 20160244577
    Abstract: The present invention provides a graphene polymer conductive film and a method of manufacturing the graphene polymer conductive film. The method uses a graphene conductive polymer as conductive filler such that the drawbacks of the conventional conductive film such as exceeded filler content, expensive, complex manufacturing process and high environment pollution. The manufacture of graphene uses the method of in situ polymerization such that the conductive polymer and the graphene are distributed more uniformly, the produced graphene conductive polymer is with good stability, and the conductivity is proved. The present invention further realizes size control of the graphene conductive polymer in the process of manufacturing the graphene conductive polymer through adjusting the ratio of raw materials of the graphene and the conductive monomers. The graphene polymer conductive film produced by the present invention has advantages of high conductivity, environment friendly, etc.

  • Publication number: 20160122456
    Abstract: The present invention provides a photoresist composition and a method of preparing the same. The photoresist composition includes a color polymer that is obtained by dye molecules grafted to a polymer molecule through chemical bonds. The photoresist composition utilizes the color polymer to replace conventional pigments to preclude conventional problems of difficult to disperse pigments in the photoresist composition, poor contrast and brightness. Since the color polymer has brilliant color, high penetration, good thermal and light stabilities, so that the photoresist composition of the present invention has better color developing effect, preferred thermal and light stabilities. The present invention provides a method of preparing a photoresist composition which reduces components in the photoresist composition and simplifies preparation process of the photoresist composition, the photoresist composition obtained thereby has better color developing effect, also has preferred thermal and light stabilities.
