摘要	With the continuous depletion of global rhenium resources, the separation and purification of rhenium (Re) from secondary resources became very important. Herein, an imprinted composite membrane with "flexible chain" thermo-responsive imprinted separation layer structure (Re-TIICM) was prepared to achieve selective separation and recovery of Re from secondary resources with complex composition. Re-TIICM's thermo-responsive imprinted separation layer occurred sol/gel phase transition by adjusting the temperature, which effectively mitigated the trade-off between selectivity and desorption. The structure and performance of Re-TIICM under optimum process conditions were tested and evaluated. The results showed that Re-TIICM exhibited a maximum adsorption capacity of 0.1036 mmol/g at 35?, a separation degree of 4.37 (MnO4- as disturbing ions), and remained good adsorption capacity and selectivity after 9 adsorption/desorption cycles. When Re-TIICM was applied in secondary resources, the purity of Re increased from 35.412% to 70.208% after one adsorption/desorption cycle, showing a great potential for industrial applications.
