4B2_0625_POLYACRYLONITRILE-LIGNIN BLENDS AS PRECURSORS FOR POROUS CARBON FIBERS

Polyacrylonitrile/lignin blends were spun by use of solvent wet spinning. The precursor fibers have been characterized by IR, rheometer, tensile tests and density calculation. Afterwards the fiber have been stabilized by means of a batch device and the stability indexes (S.i.) were assumed through differential scanning calorimetry.
