Luo et. employed a novel method that involved deconstructing and reconstructing pyrolytic lignin to produce a new precursor with high molecular orientation. First, the lignin bio-oil was repolymerized. Repolymerization was performed by converting lignin bio-oil into acrylate monomers, which subsequently underwent radical polymerization to produce an acrylate polymer with aromatic pendants. Ideally, this method would transform amorphous lignin into an orientable polymer without compromising its carbon content and thermal stability. This repolymerization converted lignin bio-oil into a new thermoplastic polymer, which was then subjected to melt-spinning followed by thermostabilization at 280°C at 10°C/min. Finally, the fibers underwent a carbonization process that involved heating them to 1000°C at 7°C/min between 25 and 500°C and 3°C/min between 500 and 1000°C. Fibers were then kept at the 1000°C temperature for an extra hour. The lignin-based carbon fibers that are generated have a significantly higher modulus and tensile strength.
