Synthesis and characterization of hybrid organic-inorganic materials based on sulphonated polyamideimide and silica [PDF]

, 2010
The preparation of hybrid organic–inorganic membrane materials based on a sulphonated polyamideimide resin and silica filler has been studied. The method allows the sol–gel process to proceed in the presence of a high molecular weight polyamideimide,
