Abstract: The present disclosure relates to a composite membrane in which a rubbery polymer is introduced into a gutter layer to suppress the physical aging of the highly permeable composite membrane, and more particularly, to a composite membrane comprising a porous support layer; a gutter layer on the porous support layer; and an active layer on the gutter layer, wherein the gutter layer comprises a blend of poly(l-trimethlsilyl-l-propyne) (PTMSP) and a rubbery polymer and a method for preparing the same. The composite membrane according to the present disclosure has high permeation performance and a remarkable decline in physical aging leading to a decrease in permeability over time and thus has very high industrial applicability.

Abstract: The present invention provides an anion-exchange composite membrane comprising a copolymer containing a vinylbenzyl trialkylammonium salt repeating unit, a styrene repeating unit and a divinylbenzene derived repeating unit; an olefin additive; a plasticizer; and a polyvinyl halide polymer.The anion-exchange composite membrane comprising a copolymer containing a vinylbenzyl trialkylammonium salt repeating unit, a styrene repeating unit and a divinylbenzene derived repeating unit; an olefin additive; a plasticizer; and polyvinylidene fluoride of the present invention not only displays low electrical resistance, excellent ion exchange capability, excellent ionic conductivity, excellent mechanical properties, excellent chemical properties, and processability, but also is easy to regulate its ion exchange capacity and ionic conductivity. Also, the composite membrane of the invention is easier to produce and cheaper to manufacture than the conventional anion-exchange composite membrane.
