چکیده مقاله:
Membrane separation processes have become one of emerging technologies during the past few decades.
Gas and liquid separation processes require a membrane with high permeability and selectivity. MMMs are
obtained by embedding a filler material such as molecular sieves and zeolites and or conductive polymer
into a polymer matrix. MMMs are expected to combine the separation properties of polymer such as
flexibility and low cost with those of zeolite such as molecular seiving action , selective adsorption ,high
mechanical strength and good thermal and chemical stability,and thus ,the resulting filler membranes can be
used on a wide range of operating condition. Some of the topics that are discussed in this review include:
1)the effect of interface morphologies on the transport properties of zeolite/polymer MMMs 2) the
polymer chain rigidification and it's effect 3) zeolite pore size 4) the amount of zeolite in MMMs 5) particle
sedimentation and agglomeration Several method for improving these factors are also suggested.
