Spirocyclic Bio-Based Epoxy Resins from Lignin-Derived Guaiacol: Molecular Design for Enhanced Thermal, Mechanical, and Hygrothermal Stability
Growing global demand for sustainable materials has driven the development of high-performance biobased epoxy resins. However, conventional strategies are plagued by reliance on fossil resources and subpar performance across key metrics (e.g., glass transition temperature, tensile modulus, and hygrothermal stability)...
