Abstract
The demand for wearable electronics has resulted in an increasing interest in
the development of functional fibers, with a specific focus upon the development of electrically conductive fibers incorporable into garments. However,
the production of thermally conductive fibers for heat dissipation has been
largely neglected. Owing to the very rapid development of miniaturized wearable electronics, there is an increasing need for the development of thermally
conductive fibers as heat sinks and thermal management processes. In this
study, thermally conductive but electrically insulating boron nitride nanopowder (BNNP) fillers are used to effectively enhance the thermal conductivity
and mechanical properties of elastomeric polyurethane fibers. Thermal conductivity enhancement of more than 160% is achieved at very low loadings of
BNNP (less than 5 wt%) with an improvement in the mechanical properties of
the unmodified fiber. These thermally conductive fibers are also incorporated
into 3D textile structures as a proof of processability.
