ABSTRACT Polyethylene (PE)/carbon nanochip fibers (CNCF) fibrillar crystals were grown under shear flow. The ranged from 25 to 200 nm in diameter and bundled form PE/CNCF macro‐fibers. further processed by hot‐drawing near the PE melting temperature. On basis of small‐angle X‐ray analysis, it was found that during drawing presence CNCF led continuous extended‐chain crystal growth. DSC peaks associated with transformation orthorhombic a hexagonal lattice phase structure (i.e., increased...
