<P><B>Abstract</B></P> <P>The carbon nanofiber-carbon nanotube (CNF-CNT) composites were fabricated by simple electrospinning and carbonization of polyacrylonitrile (PAN)-CNT solution prepared by first sonicating and stirring the CNT in N, N-dimethylformamide (DMF) as solvent. Aniline monomer was then coated on the composite materials via in situ chemical polymerization to form CNF-CNT-PANI composite. The as-prepared samples were then characterized. Importantly, the dispersed CNTs in the CNF-CNT composites were crucial for the CNF-CNTs acting as supports for the CNF-CNT-PANI composites to attain high electrochemical properties. The composite electrode material is found to be used as effective electrode material for supercapacitors with specific capacitance as high as 1119 F g<SUP>−1</SUP>at 1 A g<SUP>−1</SUP> compared to the bare CNF film with a specific capacitance of 278 F g<SUP>−1</SUP>. The composite electrode displaced excellent cyclic stability with retention of 98% even after 2000 cycles at a current density of 10 A g<SUP>−1</SUP>.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
