▎ 摘　　要

NOVELTY - Preparing protein absorbing material comprises adding a nanocomposite material to graphene material as a base material. The graphene material and the nanocomposite material have unique two-dimensional structure and surface properties. USE - The method is useful for preparing absorbing material that is useful in study of separation, purification and analysis of protein and for large-scale biological downstream processing applications. ADVANTAGE - The method is capable of preparing the material with rapid absorption property.
