Neck-size distributions of through-pores in polymer membranes

▸ Effects of membrane parameters on capillary flow porometry were studied. ▸ Pore-architecture was studied by microscopy and growing gold nano-rods in pores. ▸ Pore-neck size distribution was found to reproducible within ±5%. ▸ Tortuosity of the pores did not affect data obtained by capillary flow porometry. ▸ The quality of pore-grafted membrane was studied by capillary flow porometry.
