Effect of binder addition on the properties of unsupported γ-Al2O3 membranes

Unsupported gamma-Al2O3 membranes prepared by the sol-gel method were characterised to determine the effect of the addition of binders including polyethylene glycol and polyvinyl alcohol. The sol-gel method involved the peptisation of a boehmite (AlOOH) sol prepared from aluminium sec- butoxide. The...
