Despite these unique properties, chicken feathers are considered a waste byproduct of the poultry industry [2]. To utilize feather waste, it was used as an additive to reinforce Polyacrylonitrile (PAN) polymer in the form of Keratin Extract. The highlight of the study is to prepare and characterize PAN with chicken feather keratin as additive by electrospinning. Keratin was extracted under reduction method with the use of sodium sulphide and solubilized with NaOH [3]. The presence of Keratin was confirmed with Fourier Transform Infrared Microscopy (FTIR) and Ultraviolet–visible Spectroscopy (UV-Vis).PAN nanofibers with different keratin loadings were formed by electrospinning process and Dimethylformamide (DMF) as solvent. The electrospun nanocomposite membranes were analyzed using Scanning Electron Microscopy (SEM), FTIR, contact angle goniometer, an...
