摘要：

Corrugated crystal morphologies of poly(ethylene succinate) (PESU) with a bird-wing shape grew from the thin-film melt with the film thickness less than 1 mum. The center of the bird-wing-shaped crystal consisted of a lozenge crystal. Corrugated steps were observed in the direction of the short axis of the lozenge crystal (b-axis). Fibrous textures extended in the direction of the long axis of the lozenge crystal (a-axis), and they wrapped around the corrugated crystals. The corrugated crystals and the fibrous textures consisted of flat-on and edge-on lamellae, respectively. The wing-shaped morphology was constructed by combining the crystal growth with the flat-on and edge-on lamellae.
