Photonic-structured fibers assembled from cellulose nanocrystals with tunable polarized selective reflection

Journal Article


Abstract


  • Fibers with self-assembled photonic structures are of special interest due to their unique photonic

    properties and potential applications in the smart textile industry. Inspired by nature, the

    photonic-structured fibers were fabricated through the self-assembly of chiral nematic cellulose

    nanocrystals (CNCs) and the fibers showed tunably brilliant and selectively reflected colors

    under crossed-polarization. A simple wet-spinning method was applied to prepare composite

    fibers of the mixed CNC matrix and polyvinyl alcohol (PVA) additions. During the processing, a

    cholesteric CNC phase formed photonic fibers through a self-assembly process. The selective

    color reflection of the composite fibers in the polarized condition showed a typical red-shift

    tendency with an increase in the PVA content, which was attributed to the increased helical pitch

    of the CNC. Furthermore, the polarized angle could also alter the reflected colors. Owing to their

    excellent selective reflection properties under the polarized condition, CNC-based photonic

    fibers are promising as the next-generation of smart fibers, applied in the fields of specific display

    and sensing.
