Hybrid cellulose membrane was formed by impregnating ultrafine particles into cellulose membrane by contacting each side of the membrane with aq. NH3 and Fe (NO3) 3 solutions. The particles layer formed was in proportion to the contact period. This hybrid membrane looked like a brownish homogeneous solid solution. The impregnated particles were directly converted into ferromagnetic Fe2O3 by thermal decomposition of the hybrid membrane. Gas permeabilities were investigated using the freeze-dried hybrid membrane. Selectivity did not appreciably change but permeability did appreciably compared to cellulose membrane without impregnation.
