Recent advances in cryogenic scanning nanobeam electron diffraction (cryo-NBED) methods have allowed extraction of the crystalline-domain morphology in organic materials such as polymer thin films and organic semiconductors [1] . Nonetheless, mapping such morphology in beam sensitive systems with suppressed crystallinity such as semicrystalline copolymer membranes used for fuel cell applications presents a new challenge [2] .
