摘要

Abstract

In this paper

the effect of hydrogen reduction of silver ions on the performance and structure of new solid polymer electrolyte polyetherimide (PEI)/Pebax2533 (Polynylon12/tetramethylene oxide block copolymer

PA12-PTMO)/AgBF

composite membranes is investigated. For PEI/Pebax2533/AgBF

composite membranes prepared with different AgBF

concentration

the permeances of propylene and ethylene increase with the increase of AgBF

concentration due to the carrier-facilitated transport

resulting in a high selectivity. But for propylene/propane mixture

the mixed-gas selectivity is lower than its ideal selectivity. The hydrogen reduction strongly influences the membrane performance

which causes the decrease of propylene permeance and the increase of propane permeance. With the increase of hydrogen reduction time

the membranes show a clearly color change from white to brown

yielding a great selectivity loss. The data of X-ray diffraction and FT-IR prove that silver ions are reduced to Ag

after hydrogen reduction

and aggregated on the surface of PEI/Pebax2533/AgBF

composite membranes.
