초록

The present invention relates to membranes and to a process for making them. The membranes according to the invention comprise a sheetlike flexible substrate having a multiplicity of openings and having a coating on and in said substrate, the material of said substrate being selected from nonwovens of polymeric fibers, said nonwovens having a porosity of more than 50% and said coating being a porous ceramic coating, said substrate preferably being from 10 to 200 μm in thickness. Such membranes provide a distinctly higher flux than conventional membranes....
