Abstract

A method of preparing a superabsorbent polymer and the superabsorbent polymer maintaining excellent basic absorption performances such as centrifuge retention capacity, while exhibiting improved gel strength and absorption rate are provided. The nanocellulose fiber is introduced during the preparation of the superabsorbent polymer to improve mechanical strength, to form a porous structure, and to rapidly absorb the surrounding water through capillary action and delivering the water to the inside of the superabsorbent polymer.
