چکیده انگلیسی
Porous membranes using synthetic polymers have been applied in several research methods and devices such as hydrophobic filters for removal of microorganisms and particles from air and other gases, and chromatography. We report in this paper a recent study of nanopore characterization fabricated in PFA thin film membranes using a homemade feedback controlled ion beam system adapted to a MeV Pelletron accelerator. Fluorpolymer membranes were bombarded with gold ions producing nanopores in a few minutes, with a diameter distribution controlled by the feedback system. The fabrication process is fast when compared with chemical etching techniques. Micro-Raman and AFM were used to characterize the pore properties.
