▎ 摘  要

NOVELTY - Polyester composite polytetrafluoroethylene oil-water separation material comprises a substrate and an emulsion film attached to the surface of the substrate. The substrate is graphene oxide, and the emulsion forming the surface coating of the substrate which includes 15-20 pts. wt. polytetrafluoroethylene, 10-15 pts. wt. polyester, 60-70 pts. wt. organic solvent, 2-5 pts. wt. cross-linking agent, and the mass ratio of the matrix to the emulsion is (1-5):100. USE - Polyester composite polytetrafluoroethylene oil-water separation material. ADVANTAGE - The polyester composite polytetrafluoroethylene oil-water separation material has high super hydrophobic and lipophilic characteristics and excellent oil-water separation effect.
