## Description

- description: We present a straightforward yet highly efficient approach for controlling
    the orientations of poly(ethylene oxide) (PEO) lamellae by introducing pseudopolyrotaxane
    nanosheets (PPRNSs), a novel class of two-dimensional fillers featuring well-organized
    polymer brushes. Grazing-incidence wide-angle X-ray scattering reveals parallel
    alignments of uniformly flat-on PEO lamellae to the film surface, and the degrees
    of their orientations are closely linked to the PPRNS concentration. Via control
    experiments and comprehensive investigations of crystallization kinetics and morphological
    evolutions of nanocomposites with different PPRNS contents, we elucidate the mechanism
    driving lamellar orientation. PPRNSs provide additional nucleation sites for PEO
    crystallization, thereby influencing the crystallization kinetics. PPRNSs, acting
    as nucleating agents, accelerate crystallization rates, impacting crystal morphology,
    crystal growth direction, and crystallinity preservation. Control experiments
    emphasize the distinct roles of polymer brushes in offering nucleation sites.
    This study lays the foundation for diverse applications and further explorations
    of PPRNS-based materials in the fields of polymer nanocomposites, surface engineering,
    and functional material design.
