Key Points

The aim is to explore how depolymerized lignin can enhance the properties of lignin-acrylonitrile copolymers for fiber production.
Analyzed the structure and characteristics of depolymerized lignin.
Created copolymers using lignin and acrylonitrile.
Evaluated the performance of wet-spun fibers derived from these copolymers.
Demonstrated improved fiber properties compared to traditional polymers.
Highlighted the potential for enhanced sustainability in carbon fiber production.
Showed feasibility for using lignin as a significant raw material.

Implication

This research demonstrates the potential of lignin-acrylonitrile copolymers for creating sustainable fibers, suggesting a pathway for renewable material use.

Abstract

The growing demand for renewable materials and the valorization of biomass by-products have positioned lignin as a promising raw material for bio-based carbon fiber (CF) production. However, its heterogeneous, branched...
