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.

Carbon nano-material pellets and a method for preparing the pellets from powder of carbon nano-material

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.
