In this work, the nickel‐based metal organic framework (Ni‐MOF) is attached to the conductive carbon cloth (CC) by using a hydrothermal reaction. In order to make MOFs strongly interacted with CC, polymeric molecules of polyaniline (PANI) are deposited on Ni‐MOF@CC employing an in–situ polymerization method. The PANI shows a three‐dimensional fiber‐network morphology. Due to the improved electrical conductivity and the porous networks, the electrochemistry property of the obtained flexible PANI/Ni‐MOF@CC is greatly enhanced compared with Ni‐MOF@CC. The specific capacitance of PANI/Ni‐MOF@CC reaches 109 F cm⁻² (573 F g⁻¹). The optimum energy density of PANI/Ni‐MOF@CC at 0.1 A cm⁻² can be 7 mWh cm⁻² with power density of 70 mW cm⁻². Because the fiber networks of PANI on MOF enhances the interactions between MOF and CC, the PANI/Ni‐MOF@CC shows high stability of 95 % capacitance retention after 5000 charge‐discharge cycling.

适用于高性能电容器的柔性固态PANI光纤网络/ Ni-MOF @ CC电极：合成和稳定性研究

在这项工作中，通过水热反应将镍基金属有机骨架（Ni-MOF）连接到导电碳布（CC）。为了使MOF与CC强烈相互作用，采用原位聚合方法将聚苯胺（PANI）的聚合物分子沉积在Ni-MOF @ CC上。PANI显示了三维纤维网络形态。由于改善了电导率和多孔网络，与Ni-MOF @ CC相比，获得的柔性PANI / Ni-MOF @ CC的电化学性能得到了极大的提高。PANI / Ni-MOF @ CC的比电容达到109 F cm ^-2（573 F g ^-1）。PANI / Ni-MOF @ CC在0.1 A cm ^-2时的最佳能量密度可以为7 mWh cm ^-2，功率密度为70 mW cm⁻²。由于MOF上PANI的光纤网络增强了MOF与CC之间的相互作用，因此PANI / Ni-MOF @ CC在5000次充放电循环后显示出95％的电容保持率的高稳定性。
