  • Publication number: 20220389218
    Abstract: The present invention relates to a novel polyaryletherketone (PAEK) polymer composition with a significantly increased crystallization rate, and preferably, to a polyetherketoneketone (PEKK) polymer composition. According to the present invention, there is provided a polymer composition including a liquid crystal polymer (LCP), an inorganic nucleating agent, a reinforcing agent, and a filler in polyaryletherketone (PAEK). Therefore, the present invention provides an effect of improving a crystallization rate of the polymer composition and improving molding processability, thereby improving productivity, shape, dimensional stability, or the like of products.

  • Publication number: 20150224479
    Abstract: A method of preparing a metal catalyst for preparing carbon nanotubes and a method of preparing carbon nanotubes using same. In one embodiment, a deposition-precipitation method is used. The method includes preparing a support dispersion solution in which a solid support is dispersed in a solvent; and injecting a metal precursor salt solution and a pH adjusting solution into the dispersion solution to prepare a mixed solution and adsorbing metal oxides or metal hydroxides formed therefrom on a surface of the solid support to prepare a catalyst particle.
