Abstract Details

An approach based on a combination of ultra small angle x-ray scattering (USAXS), ultra small neutron scattering (USANS), and static light scattering (SLS) is proposed to characterize microporous membrane filters. The porosity, pore size (average pore chord), sample density of MCE (a mixture of nitrocellulose and cellulose acetate with nominal pore sizes from 0.025 to 1.2 µm), PVDF (Polyvinylidene fluoride with nominal pore sizes from 0.1 to 1.2 µm), Nylon (pore size 0.1 µm) and Anopore Whatman (top 0.02 µm bottom 0.2 µm) membranes were obtained from the scattering data. The calculated pore sizes were three times larger than the rated pore size given by the manufacturer. The sample densities calculated from the scattering data are consistent with the densities reported elsewhere. Our approach also yields the average size (chord) of the skeletal strut of the membrane. Therefore, scattering techniques in conjunction with the approach elucidated provide detailed structural information on the microporous membranes with pore sizes from 0.025 to 1.2 µm.
