  • Patent number: 11332617
    Abstract: A polyarylene sulfide resin composition contains a polyarylene sulfide resin, a transition metal particle, a fibrous inorganic filler, and an inorganic nucleating agent, and a molded article made from the resin composition. The resin composition has excellent mechanical, corrosion, and haze properties, and heat resistance. The resin composition prevents corrosion of a mold and deterioration in the durability of a manufactured product upon injection by effectively removing halogen-based impurities, and also has excellent mechanical, corrosion, and haze properties, and heat resistance. A molded article manufactured from the resin composition satisfies the standards required for components of a vehicle and an electric/electronic device.

  • Patent number: 9837180
    Abstract: Disclosed are a carbon nanomaterial pellet and a method for preparing same. More particularly, it relates to a carbon nanomaterial pellet having a specific size and a high apparent density prepared by a simple process using only a rotary tablet press without mixing a carbon nanomaterial powder with a solvent or an additive, which is capable of solving the powder dust problem occurring when preparing a polymer composite from a carbon nanomaterial in the form of powder, thus improving physical properties and remarkably reducing cost of packaging and transportation, and a method for preparing the carbon nanomaterial pellet from a carbon nanomaterial powder.

  • Patent number: 9576706
    Abstract: Disclosed is a method for preparing a carbon nanomaterial/polymer composite. More particularly, it relates to an improved method for preparing a carbon nanomaterial/polymer composite capable of solving a dust problem of a carbon nanomaterial powder and a layer separation problem due to large density difference between the carbon nanomaterial powder and a polymer pellet and providing superior physical properties of the composite, whereby an additive used to prepare the carbon nanomaterial/polymer composite is mixed with the carbon nanomaterial powder and prepared into a pellet, which is then mixed with the polymer pellet.
