Composite silica/Nafion ยฎ membranes were prepared using a tetraethylorthosilicate (TEOS) hydrolysis sol-gel reaction followed by solution casting. Physico-chemical properties of the composite membranes were characterized by TGA, XRD, FT-IR, SEM-EDX and water uptake. Membranes were investigated in di
A~tract--Solution-cast films of segmented polyurethanes based on poly(ethylene adipate)glycol, 4,4'-diphenylmethanediisocyanate and 1,4-butanediol have been investigated. Optical and electron microscopic studies revealed different amounts of birefringent aggregates, related to the casting temperatur
