Abstract Proton conducting hydrophilic channels were created successfully in poly (ether ether ketone)
(PEEK) by means of step by step modification followed by the optimization of sulfonation
process (SPEEK70, DS=68.57%). Although highly sulfonated PEEK has excellent proton
conductivity, it lacks in mechanical stability due to low swelling degree. Therefore, a potential
method has been proposed in this work by integrating poly (sulfone) and nanosilica (SiO2
) into
SPEEK matrix. SPEEK 70 (S) was utilized to prepare blended nanocomposite membranes for
further enhancement of hydrophilic channels. The blended nanocomposite membranes are,
SPEEK/SiO2
as SNS, SPEEK blended with poly (sulfone) as SP, SPEEK… More >
