摘      要：Nanostructured porous polyaniline(PANI)has been synthesized and coated simultaneously on a highly flexible and conductive carbon cloth(CC)substrate using a simple in-situ chemical oxidative polymerization *** coated CC(PANI-CC)based flexible electrodes were further used for the fabrication of flexible supercapacitor *** the comparison purpose,pure PANI has also been synthesized and tested for its electrochemical *** energy storage capacity of PANI and PANI–CC composite was investigated using electrochemical techniques like CV,GCD,and EIS in a potential range from 0 to 0.8 V in 1 M H_(2)SO_(4)***-CC flexible electrodes exhibited the highest specific capacitance of 691 F/g;whereas,pure PANI could only achieve 575 F/g of specific capacitance at 1 A/*** also exhibited outstanding cyclic stability by recollecting 94%of its initial capacitance after 2000 GCD *** actual implementation,a flexible supercapacitor device has been fabricated using stainless steel sheets and PANI-CC flexile *** energy storage performance of the PANI-CC flexible supercapacitor device was tested at several bending angles,which resulted in 72%of capacitance retention at a maximum bending angle of 140°compared to the capacitance obtained at an angle 0°(flat state).PANI-CC exhibited improved electrochemical performance than pure PANI due to the synergistic effect between PANI and ***,CC helped in enhancing the conductivity and stability;whereas,PANI boosted the capacitance owing to its excellent porosity and fast pseudocapacitive charge storage response.
