Abstract
Mechanical properties of rod7like cellulose nanocry
stals (CNCs) offer great potential as
bioderived reinforcement in (nano)composites. Polyv
inyl alcohol (PVOH) is a useful
industrial material and very compatible with CNC ch
emistry. High performance CNC/PVOH
composite fibers were produced coaxial coagulation
spinning, followed by hot7drawing. DSC
and WAXS showed that CNCs increase the alignment an
d crystallinity of PVOH, as well as
providing direct reinforcement, leading to enhanced
fiber strength and stiffness. At 40 wt.%
CNC loading, the strength and stiffness reached 880
MPa and 29.9 GPa, exceeding the
properties of most other nanocellulose based compos
ite fibers previously reported.
