Polyacrylonitrile-based, submicron, sea-island, carbon fibers were prepared with polyacrylonitrile (PAN) islands in a polyvinly alcohol (PVA) sea. Mixtures of PAN and PVA were wet-spun and characterized. DSC thermograms showed phase-separated PVA and PAN, indicating the resultin fibers' sea-island structures. SEM images showed PAN fibers of 250~400 nm diameter remaining after removal of PVA by immersion in boiling water. The PAN fibers were stabilized and carbonized, their diameter decreased to 100~200 nm depending on the mixing ratio of PAN to PVA. XRD showed typical turbostratic structures of the carbon fibers.
