Functionalisation of nylon with carbon nanotubes to make thermally stable fabric and wearable capacitor

Single-walled carbon nanotubes (SWCNT) are dispersed in water and attached to nylon fabric by a simple immersing-drying procedure, which is evidenced by data obtained using Raman spectroscopy, scanning electron microscopy and transmission electron microscopy. Thermalgravimetric analysis reveals the temperature at which the functionalised nylon fabric reaches its maximum weight loss rate increases about 10^oC with respect to the pristine nylon. This improvement in thermal oxidation stability can be ascribed to the strong free-radical accepting capacity of nanotubes and their high thermal conductivity. The SWCNT functionalised nylon is then used to make a capacitor structure, which possesses the merits of being lightweight, little hysteresis and low power dissipation.
