Membranen aus (per)fluorinierten amorphen Polymeren

摘要

Porous membranes of (per)fluorinated amorphous polymers having a porosity in the range 5-500 nm, preferably 20-100 nm, measured by an atomic force electronic microscope; the membrane pore average size ditribution being narrow, about 80%-90% of the pores have a size ranging from minus 5 nm to plus 5 nm of the value of the distribution maximum peak.
