| Abstract: |
The ability to maintain body temperature has been shown to bring about improvementsin sporting performance. However, current solutions are limited with regards to flexibility, heatinguniformity and robustness. An innovative screen-printed Nanocarbon heater is demonstrated whichis robust to bending, folding, tensile extensions of up to 20% and machine washing. This combinationof ink and substrate enables the heated garments to safely flex without impeding the wearer. It iscapable of producing uniform heating over a 15 × 4 cm area using a conductive ink based on a blendof Graphite Nanoplatelets and Carbon Black. This can be attributed to the low roughness of theconductive carbon coating, the uniform distribution and good interconnection of the carbon particles.The heaters have a low thermal inertia, producing a rapid temperature response at low voltages,reaching equilibrium temperatures within 120 s of being switched on. The heaters reached the 40 ◦Crequired for wearable heating applications within 20 s at 12 Volts. Screen printing was demonstratedto be an effective method of controlling the printed layer thickness with good interlayer adhesionand contact for multiple printed layers. This can be used to regulate their electrical properties andhence adjust the heater performance. |
