In this work, ultrathin Poly[1-(trimethylsilyl)-1-propyne] (PTMSP) layer with improved permeance for organic solvent was successfully fabricated on polysulfone substrate by knife–casting method. Next, hyper-crosslinked-polymer PAF-1 and PDCX were introduced into PTMSP. The nanoporous additives provide additional passageways to solvents, enhancing the organic solvent nanofiltration (OSN) performance of the PTMSP materials further. The best performance of membrane showed a permeance of 40.5 L m-2 h -1 bar-1 for methanol and 95% Rose Bengal (1017.6 g mol−1) rejection. The newly developed ultrathin PTMSP/hyper-crosslinked-polymer composite membrane is highly scalable and robust, whilst enhancing OSN membrane performance.
