Crystallinity and thermal property were evaluated for polyethylene, polypropylene, polystyrene films, then, they were irradiated with atomic oxygen (AO) and observed by a scanning electron microscope and positron annihilation lifetime spectroscopy. Free-volume holes and thermal motions affected spatial scales for the reactions with AO, determining the sizes and numerical density of formed protrusions.
