“…Polymer filtration membranes are of great interest due to their potential applications in drug delivery,[1,2] biomolecule separation,[3,4] water and air purification,[5] biological and chemical sensing,[6–9] battery separators,[10] fuel cells,[11] and catalysis. [12] Various polymer membranes with narrowly distributed pore sizes ranging from the nano to micron-scale have been prepared using myriad techniques such as track-etching, selectively etching block copolymers, reverse templating etc.…”
