Insight into the structure and mechanical performance of high content lignin reinforced poly (vinyl alcohol) gel‐spun fibers via the regulation of esterified hydrophilic lignin composition for better sustainability

Lignin is an effective low‐cost renewable reinforcement material for composite fibers at low concentration. In general, reinforcing synthetic polymeric fibers with high content lignin are preferred due to the fibers' enhanced sustainability. However, aggregation and disruption of fiber crystall...
