a H2/CO2 separation performance of the PES@GF and TpPa-1@PES@GF-X membranes as a function of reaction time (Data are presented as mean values ± s.d. (standard deviation), n = 3). b H2/CO2 separation performance of the TpPa-1@PES@GF-72 membrane mixed at different temperatures. c Temperature‒gradient evaluation of the H2/CO2 separation performance of the TpPa-1@PES@GF-72 membrane mixed. d Gas separation schematic diagram of traditional COF-MMMs, where COF nanoparticles are distributed on the cross-section of the membrane. e Gas separation mechanism of COF-MMMs prepared via NIPS-triggered in situ IP strategy, where the COF membrane is distributed on the surface of the polymer matrix. f Long-term stability test of the TpPa-1@PES@GF-72 membrane under continuous operation. g Digital photograph of the scaled-up fabricated COF-MMMs. h Mixed H2/CO2 separation performance of 9 portions.
