Graphite-Doped Polyacrylonitrile Nanofiber Mats for Polymer Composite Pipeliners: Absorption Characterization

Internal corrosion in pipelines is the most critical factor for pipeline failure. The growing trend of mitigating internal corrosion in pipelines by using nanofiber polymer composite liners was investigated in this study. The liners were fabricated using the electrospun Polyacrylonitrile (PAN) and graphite-doped PAN nanofibers. The liners were tested by immersing in water at 23 °C, 50 °C, and light oil to determine the diffusion characteristics. The absorption results combined with ATR-FTIR results confirmed that the addition of graphite-doped nanofibers has controlled the absorption significantly.
