Figure 6. PFPIM membranes for crude oil separation. (A) Family of the SBAD materials (SBAD-1 to SBAD-4) and computational modeling of pore surfaces for the SBAD family and PIM-1, where teal represents accessible (interconnected) pores, and magenta represents nonaccessible pores^[64]; (B) Preparation and hydrocarbon separation performance of solution-processable spirocyclic polytriazoles^[98]. PFPIM: Polar groups-functionalized polymers of intrinsic microporosity; SBAD: spirobifluorene aryl diamine; PIM: polymers of intrinsic microporosity.
