Definitions

  • the invention relates to organic/inorganic hybrid polymer blends and hybrid polymer blend membranes, that are composed of:
  • an element oxide or element hydroxide or metal oxide or metal hydroxide obtained by the hydrolysis and/or the sol/gel reaction of an element organic and/or metal organic compound during the membrane formation process and/or by subsequently treating the membrane in aqueous acidic, alkaline or neutral electrolytes.
  • the invention farther relates to hybrid blends and hybrid blend membranes containing polymers that carry SO 3 H, PO 3 H 2 and/or COOH groups, obtained by aqueous, alkaline or acidic hydrolysis of the polymeric acid halides contained in the polymer blend or the polymer blend membrane.
  • the invention also relates to methods for producing said hybrid blends and hybrid blend membranes.
  • Nafion sulfonyl fluoride precursor membranes are preswollen in perfluorohydrophenanthrene and immersed in 3-aminopropyltriethoxysilane. Thereafter excess silane is washed out with EtOH. Hybrids are formed, in which by hydrolysis of silane and by reaction of silanes with SO 2 F groups SiO 2 networks partially cross-linked with the polymer are formed in the membrane matrix 1 .
  • An object of the invention is to provide composites and composite membranes of polymeric acid halides containing in addition an inorganic element/metal oxide/hydroxide phase, which improves the following membrane properties:
  • organic precursors of element/metal oxides/hydroxides are brought into the polymer solution (alkoxides/esters, acetylacetonates etc).
  • tie inorganic phase in the ionomer happens after the membrane formation by hydrolysis in acidic, alkaline and/or neutral aqueous environment, whereby optionally at the same time or in another step the polymeric acid halide groups may be hydrolyzed to acid groups.
  • zirconium(IV) propylate 70, weight % in 1-propanol, Zr(OCH 2 CH 2 CH 3 ) 4 is brought into solutions of PSU sulfochloride in tetrahydrofuran, the zirconium(IV) propylate does not hydrolyze in the polymer solution or form a sparingly soluble complex, but is built into the membrane matrix upon evaporation of the solvent.
  • zirconium(IV) propylate solution in propanol would be mixed with a solution of PSU sulfochloride (or PSU sulfonic acid or PSU sulfonic acid salt) in a dipolar aprotic solvent like N-methylpyrrolidinone, zirconium(IV) propylate would immediately hydrolyze or precipitate.
  • the organic Zr compound can be hydrolyzed by successive posttreatment of the membrane in aqueous lye and/or water and/or acid to zirconium dioxide or zirconium oxide hydroxide nanodispersed in the membrane matrix.
  • the inorganic zirconium compound can be detected by EDX in the membrane matrix.
  • organometallic compounds like Ti(acac) 2 (OiPr) 2 can be mixed with PSU sulfochloride solutions in ether solvents without hydrolysis in the polymer solution and built into the membrane matrix upon evaporation of the solvent.
  • At least one salt, element oxide or element hydroxide or metal oxide or metal hydroxide obtained by hydrolysis of the following classes of element organic and/or metal organic compounds:
  • metal acetylacetonates e.g. Ti(acac) 4 , Zr(acac) 4
  • dipolar-aprotic solvents such as N-methylpyrrolidinone (NMP), N,N-dimethylacetamide (DMAc), N,N-dimethylformamide (DMF), dimethylsulfoxide (DMSO) or sulfolane or ether solvents such as tetrahydrofuran, dioxan, glyme, diglyme, triglyme.
  • NMP N-methylpyrrolidinone
  • DMAc N,N-dimethylacetamide
  • DMF N,N-dimethylformamide
  • DMSO dimethylsulfoxide
  • ether solvents such as tetrahydrofuran, dioxan, glyme, diglyme, triglyme.
  • the permselectivity of the membranes changes also for nonionic permeating molecules (e.g. gases).
  • the new inorganic/organic hybrid membranes according to the invention show an excellent profile of properties:
  • Some membranes according to the invention show, caused by the inorganic oxide/hydroxide in the membrane matrix, an improved water holding ability especially at T>80° C. It is supposed, that the nanodispersion of the inorganic component in the membrane is the reason behind.
  • oxide powders into ionomer membranes as has been proposed in some publications 4 already, such a fine distribution of the inorganic component in the membrane matrix as with the method according to the invention can not be reached, where the element—organic/metal organic compounds are hydrolyzed only in the membrane matrix to the oxide or (hydrogen)phosphate.
  • the membranes according to the invention show further advantages:
  • the membranes are photochemically active, especially those with nanodispersed titanium dioxide.
