Nanoporous Double-Gyroid Structure from ABC Triblock Terpolymer Thick Films

(a) Schematic representation of the DG unit cell (a cube with sides equal to ) showing only the (red and blue) intermaterial dividing surfaces (IMDSs) separating the two interpenetrating three-dimensional continuous networks from the matrix (left). To apply the H-P law, each network made of interconnected tubes was simplified to a tortuous nanochannel having a circular cross-section (right). (b) Water fluxes, , of the NIPS-made PS-b-P2VP-b-PEO/PS-b-PEO materials exposed to a CHCl₃ vapor for different times: (red dots) 0 min and (blue dots) 5 h. The error bars are the standard deviations of the mean relative flux values calculated for 3 different samples.
