摘要:木质素是自然界中储量最丰富的天然高分子之一，也是造纸工业中的主要副产物。其可再生性和优越的理化性能是制备低成本民用碳纤维的理想原材料，既实现了木质素的高值化利用，又可以降低碳纤维的成本。本文对国内外木质素基碳纤维的研究进展进行了归纳总结。

Abstract:Lignin is one of the most abundant biomacromolecules and the main by-product of papermaking industry. The excellent thermal stability, high carbon content, and sustainability make lignin an attractive choice for precursor material of civilian carbon fibers. The utilization of lignin not only reduces the cost of carbon fibers production but also enhances the sustainability and cost-effectiveness of pulp and paper industries. This review summarizes the research progress and main research results of lignin-based carbon fibers at home and abroad.
