Cellulose-Refined Cholesteric Liquid Crystal Films with Both Right- and Left-Handed Circularly Polarized Light Reflection.

ABSTRACT: Biomass-refinery enables sustainable production of viable fuels and materials. Cellulose has garnered significant attention as the most earth-abundant renewable polymer. Hydroxypropyl cellulose (HPC) derivatives are known to self-organize cholesteric liquid crystal (CLC) mesophase with right-handed macromolecular sense, leading to the chiroptical effect of right-handed circularly polarized light (CPL) reflection. In this report, we establish a promising strategy to prepare solid-state CLC films with both right- and left-handed CPL reflection by shearing chemically modified cellulose derivatives. A key piece of equipment is the rheometer with precisely tunable shear conditions. Both-handed CPL reflection arises from shear-induced enhancement in optical retardation over 300 nm by distorting
