example 1
[0035] First, 0.5g of PIM-1 powder was dissolved in 10mL of chloroform solution and stirred for 1.5h to prepare a uniformly mixed PIM-1 solution; 0.3g of ZIF-8 was dissolved in 10mL of DMF solution and stirred for 2h to obtain a ZIF-8 solution; 0.25g of UIO -66-NH 2 Dissolve in 10mL DMF solution and stir for 2h to obtain uniform UIO-66-NH 2 solution; take 2mL ZIF-8 solution in the above 10mL PIM-1 solution, stir for 1h to obtain a uniformly dispersed mixed solution; then add 2mL UIO-66-NH 2 The solution was added to the mixture of the above two solutions, and stirred for 1 h to obtain a uniform PIM-1 / MOFs solution; the solution was injected into a petri dish with a syringe, and the mixed matrix film was obtained after the solvent evaporated naturally at room temperature to form a film.
[0036] Gas separation test was carried out on this membrane; the single-component CO 2 and CH 4 Permeability of the membrane results in CO 2 The permeability is 13231barrer, for CH 4 The ...
