Ruthenium nitride was successfully deposited on a multiwalled carbon nanotube (MWCNT) forest grown on a stainless-steel mesh substrate by radiofrequency plasma-assisted pulsed laser deposition. This novel dry fabrication method for flexible supercapacitor electrodes eliminates toxic byproducts and the need for any binder component. Experimental results show a successful thin film coating of the individual MWCNTs with RuN under various synthesis conditions. The electrochemical characterization demonstrates a significant improvement in capacitance of the synthesized RuN-MWCNT electrode compared to the bare MWCNT forest, with a large potential window of 1.2 V. Capacitance values as high as 818.2 F g (37.9 mF cm) have been achieved.
通过射频等离子体辅助脉冲激光沉积法，成功地将氮化钌沉积在生长于不锈钢网基底上的多壁碳纳米管（MWCNT）阵列上。这种用于柔性超级电容器电极的新型干法制造方法消除了有毒副产物，并且无需任何粘合剂成分。实验结果表明，在各种合成条件下，单个MWCNT均成功地被RuN薄膜包覆。电化学表征显示，与裸露的MWCNT阵列相比，合成的RuN-MWCNT电极的电容有显著提高，其具有1.2 V的大电位窗口。已实现高达818.2 F g（37.9 mF cm）的电容值。
