A convenient and large-scale fabrication of ordered micron-sized porous polyimide film†
Abstract
An ordered micron-sized honeycombed macroporous polyimide (PI) film was efficiently fabricated from polyamic acid-b-polystyrene (PAA-b-PS) copolymer. The synergistic effect of the hydrogen bonding and π–π interaction contributes to the generation of this distinct morphology of PAA-b-PS.
