Abstract

bokerSelf-assembled membranes offer a promising alternative for conventional membrane fabrication, especially in the field of nano-filtration. However, recent advances pushing the developments in self-assembled membranes towards thinner membranes with more selectivity are still limited with respect to active permeation area, stability and responsiveness. Here we introduce a new pore-making strategy which involves stimuli responsive protein-polymer conjugates self-assembled across a large area of 5 cm2 using drying-mediated interfacial self-assembly. Proteins are used as a sacrificial template which – upon denaturing – provide hydrophilic pores of…
