First, a screening was performed with thick flat membranes made of the 4,4’-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) and three different amines: 2,2′-bis(4-aminophenyl)hexafluoropropane (6FpDA), 2,4,6-trimethyl-m-phenylenediamine (TMPD), and 2,3,5,6-tetramethyl-1,3-phenyldiamine (durene). As a result, 6FDA-TMPD was selected for the fabrication of defect-free hollow fiber-thin film composite membranes (HF-TFCM) due to its superior performance for the separation of R-32. These HF-TFCMs showed excellent separation performance to reclaim highpurity R-32 (permeate concentration >99 vol%) from the commercial binary blends R-410A and R-454B (a mixture of R-32 and R-1234yf). In addition, we report for the first time the membrane recovery of R-32 from the ternary blend R-407C (R-32/R-134a/R-125 38.2:43.8:18 vol%). Eventually, the separation of CO2 from synthetic gas mixtures of CO2/CH4 (50:50 vol%) and CO2/N2 (15:85 vol%) was performed for benchmarking, showing that the prepared HF-TFCM kept the separation performance of the 6FDA-TMPD thick membranes.Projects PID2019-105827RBI00, PID2022-138028OB-I00, PID2020-118547GB-I100, PID2019- 109403RB-C22, PID2019-109403RB-C21 by the Spanish State Research Agency and partially by the European Fund for Regional Development (EU), and the Regional Government of Castilla y Le´on (project VA224P20).
