Influence of Preparation Process on Morphology and Conductivity of Carbon Black-Based Electrospun Nanofibers

AbstractIn this work, three different methods of preparation of polyacrylonitrille (PAN) with carbon black (CB) solutions further used in electrospinning for producing conductive fiber mats are discussed. CB is used as conductive filler. Content of CB in polymer matrix is varied, CB/PAN = 1/2, 1/1, and 3/2. The solution properties and obtained fiber morphology are analyzed. The effect of preparation on fiber morphology and conductivity is analyzed, as well as the effect of sonication on solution properties, morphology, and conductivity of PAN+CB samples.Keywords: composite conductive fiberselectrospinningpolymer with carbon blackeffect of preparation procedure FundingThe present study was financed by Archimedes Foundation under grant no.
