Graphene(GE) was employed to increase the hydrophobic property of polypropylene (PP) hollow fiber membranes and hot solvent treatment was used to strengthen the combination of GE with PP hollow fiber membrane. Dimethylbenzene(DMB) as the solvent was used at different temperatures in this study. The stacked and folded GE sheets on the GE-coated PP hollow fiber membranes was observed using a scanning electron microscopy (SEM). In addition, the water contact angle and water entry pressure increased significantly compared to untreated PP hollow fiber membrane. The process of GE-coated PP hollow fiber membrane used for kerosene-water separation was measured with a laboratory-scale continuous setup under -0.09MPa. It demonstrated that the GE-coated PP hollow fiber membranes can achieve continuous oil-water separation and exhibits good durability and reusability. This approach provides a workable method of preparing GE functionalized PP hollow fiber membrane.
