Pore characteristics and electrochemical properties of the carbon nanofibres of polyacrylonitrile containing iron–oxide by electrospinning

The present work is novel in its preparation method to produce well–dispersed iron oxide nanoparticles in PAN nanofibres. In a in–situ process of producing carbon nanofibres in which (polyacrylonitrile) PAN incorporated with iron oxide particles using electrospinning method. This type of in situ preparation method, to produce iron oxide nanoparticles in PAN matrix was attempted to control mean particle size as well as to create uniform size pores on the web matrix, giving improved properties after thermal treatment at 1000?C. Their large surface areas coupled with good electrical conductivity and porous nature make them useful materials in the fabrication of efficient electrodes for supercapacitors. Utilising the combined techniques viz., field emission scanning electron microscope (FE–SEM) and transmission electron microscope (TEM), their well defined structures are assessed to find that CNFs with diameters ranging from 100 nm to 600 nm were produced after the alkali treatment. It is believed that quick ...
