The surface textures of the plastic pellets could be clearly illustrated in SEM images.Virgin plastic pellet and weathered plastic pellet were studied by scanning electron microscopy (SEM).Because the surface textures of the weathered plastic pellets were heterogeneous, visualization was repeated at different surface sites (at least three relatively smooth or rough sites; Wang et al., 2017).In addition, comparisons of the changes in the surface textures of virgin plastic pellets and weathered plastic pellets were carried out.
