Abstract
        In this work is reported a FT - IR analysis performed both on polyimide polymeric matrix and on polyimide selective 
membranes. Through the FT-IR study done it was shown that the water from the aqueous electrolyte solution acts on 
polyimide completing its imidization. Also, it was put in evidence that water molecules exists absorbed on the membrane’s 
surface. The result complies with other experimental results previously obtained by performing a.c. impedance analysis and 
thermal analysis.
