High-Lignin Polyurethane Foams via a Eutectic-Like Polyol Strategy: Enabling Scalable Processing and Enhanced Structural Performance
Yanpeng Luo, Jinyuan Cheng, Guigan Fang, Pedram Fatehi et autres
Abstract Replacing petroleum-derived polyols with lignin in polyurethane foams is essential for increasing renewable carbon utilization but is hindered by lignin’s heterogeneity, poor solubility, and limited reactivity. Here, we report a hydrogen-bond-engineered, eutectic-like polyol platform based on polyethylene glycol (PEG) and salicylic …
