The present invention relates to a carbon nanotube fiber and methods for preparing the same. In one embodiment, a method for preparing a carbon nanotube fiber comprises reacting a carbon source in the presence of a catalyst and a catalytic activator to form carbon nanotube aggregates, contacting the carbon nanotube aggregates with graphene oxide, and forming the carbon nanotube aggregates in contact with the graphene oxide into a carbon nanotube fiber.

Method for preparing carbon nanotube fiber and carbon nanotube fiber prepared thereby

The present disclosure relates to a preparation method of super absorbent polymer granules and super absorbent polymer granules prepared according to the same. More specifically, the preparation method of the present disclosure includes the steps of: forming a hydrogel polymer by carrying out a thermal polymerization or a photopolymerization of a monomer composition including a water-soluble ethylene-based unsaturated monomer and a polymerization initiator; drying and pulverizing the hydrogel polymer; classifying the pulverized polymer into a first fine powder having a particle size of 150 &#x3bc;m or less, and a base resin having a particle size of 150 &#x3bc;m or more and 850 &#x3bc;m or less; surface-crosslinking the base resin; classifying the surface crosslinked base resin to separate a second fine powder having a particle size of 150 &#x3bc;m or less; and forming fine powder granules by mixing the first fine powder, the second fine powder, and silica in a wet state.
