Method of preparing ceramic composite membrane and the ceramic composite membrane thereby

摘要

Disclosed is a method for manufacturing a ceramic composite membrane which comprises the steps of: coating graphene oxide on a ceramic support (step 1); coating ceramic sol on the graphene oxide coated on the ceramic support in step 1 (step 2); and sintering the ceramic support coated with the graphene oxide and the ceramic sol on the graphene oxide in step 2 to remove the graphene oxide and form a ceramic separation layer (step 3). According to the present invention, a ceramic composite membrane having excellent water permeability and an excellent rejection rate against contaminants is manufactured.
