Soluble sulfonated naphthalenic polyimides as materials for proton exchange membranes

A series of sequenced sulphonated naphthalenic polyimides with improved solubility were prepared by polycondensation in m-cresol using aromatic diamines containing phenylether bonds and/or bulky groups. Sulphonated polyimides were characterized by nuclear magnetic resonance (NMR) and infrared (IR) s...

Summary:A series of sequenced sulphonated naphthalenic polyimides with improved solubility were prepared by polycondensation in m-cresol using aromatic diamines containing phenylether bonds and/or bulky groups. Sulphonated polyimides were characterized by nuclear magnetic resonance (NMR) and infrared (IR) spectroscopies. Membranes were prepared by solution casting method and characterized by determining the ion-exchange capacity, water swelling, proton conductivity whereas the morphology of polymer membranes was studied by small angle neutron scattering.
