    Abstract Semicrystalline polymers are extensively used in various forms, including fibres, films, and bottles. They exhibit remarkable properties, e.g., mechanical and thermal, that are governed by hierarchical structures comprising 10–20-nm-thick lamellar crystals. In 1957, Keller deduced that long polyethylene (PE) chains fold to form thin single lamellar crystals, with the molecular chains perpendicular to the flat faces of the crystals (the chain-folding model). Chains inclining to the perpendicular orientation in single crystals have since been reported, along with their effects on the physical properties of PE. For bulk specimens, the chain tilt angle (φ) has been investigated only for model samples with well-annealed internal structures. However, for briefly annealed specimens, the φ values of lamellae and their origins are controversial owing to the disordered lamellar morphology and orientation. Herein, we report the direct determination of molecular-chain orientations in the lamellar crystals of high-density PE using a state-of-the-art electron-diffraction-based imaging technique with nanometre-scale positional resolution and provide compelling evidence for the existence of lamellar crystals with different inner-chain orientations. Clarifying the nanoscale variation in lamellar crystals in PE can allow precise tuning of properties and expedite resource-saving material design.

    The typical morphology of polymer crystals is plate-like crystals (lamellar crystals) with a thickness of about 10 nm. However, their original structure and structure formation mechanism still need to be fully understood. Since Keller revealed the structure of polyethylene single crystals, it was suggested that the folding polymer chains tilt with respect to the normal of the lamellar crystal surface （chain tilt）.The chain tilt inside the lamellar crystals has remained ambiguous due to the lack of proper analytical techniques. Nanodiffraction imaging （NDI）, a state-of-the-art electron microscopy technique, makes it possible to image the polymer chains tilting inside the lamellae. Such knowledge advances a deeper understanding of the thermodynamics of polymer chains in lamellar crystals.
