N2 - The great significance of boosting the design of percolating nanopore structures in block copolymers (BCPs) for varied use cases has been widely demonstrated in the past several decades. However, it still remains challenging to prepare the desired porous structures in a rapid, facile, and universal manner. Here we develop an unconventional and benchtop strategy to rapidly generate the nanoporous BCPs with arbitrary structural characters regardless of the BCP bulk morphology. This universal pore-forming strategy enables the sustainable CO2-based BCPs to form the advanced membranes with 1 s soaking for efficiently rejecting 94.2% brilliant blue R (826 g/mol). At the same time, the water permeance retains around 1020 L/(m2·h·bar), which is 1~3 orders of magnitude higher than that of other membranes. This strategy may offer a fantastic opportunity to introduce percolating pore structures in those newly developed BCPs with which the previously reported pore-forming methods may not deal.
