Fabrication of microporous polyaryl nanofilm at the liquid-liquid interface for selective molecular separation

Polymeric membranes with precise molecular weight cutoffs are necessary for molecular separations. Here, we present a stepwise preparation of microporous polyaryl (PAR_TTSBI) freestanding nanofilm as well as the synthesis of bulk polymer (PAR_TTSBI) and fabrication of thin film composite (TFC) membrane, with crater-like surface morphology, then provide the details of separation study of PAR_TTSBI TFC membrane.
