利用创新的石墨烯气凝胶自组装工艺在铜线上制备了可穿戴的线形超级电容器。该工艺的创新之处在于，据我们所知，首次采用水热石墨烯合成非平面衬底的原位覆盖。计算出单位长度的比电容约为12.5 mF/cm。该装置可以承受反复的充放电和弯曲循环，而不会遭受比电容的显著恶化。石墨烯气凝胶自涂层方法、柔性和优越的电化学性能使该器件成为电子纺织应用的合适电源。(C) 2016 Elsevier Ltd.版权所有。
Wearable wire-shaped supercapacitors were fabricated exploiting an innovative graphene aerogel self-assembly procedure on copper wire. The innovative aspect of the proposed procedure lies in the employment, for the first time to the best of our knowledge, of a hydrothermal graphene synthesis for an in situ coverage of a non-planar substrate. Specific capacitance per unit length was calculated to be about 12,5 mF/cm. The device can sustain repeated charge-discharge and bending cycles without suffering significant deterioration of specific capacitance. The combination of graphene aerogel self-coating method, flexibility and superior electrochemical performance makes the proposed device a suitable power source for e-textile applications.
