Bio-Based Fluorescent Epoxies: Emission Control through Molecular Packing and Phase Separation.

ABSTRACT: This study demonstrates the sustainable conversion of agricultural waste into high-performance fluorescent epoxy resins through direct blending of coumaric acid epoxy (CE) and ferulic acid epoxy (FE) derived from corn stover. These bio-based resins exhibit tunable photoluminescence, with emission maxima shifting from 299 nm to 841 nm as FE content increases from 0 to 33 wt%. In contrast, blends based on commercial bisphenol A diglycidyl ether (BADGE) reach emission saturation around 550 nm and exhibit phase separation at higher FE concentrations, as confirmed by light microscopy. The synthesized CE-FE blends achieve superior or comparable thermomechanical properties, including flexural moduli (3.2-3.4 GPa), glass transition temperatures, and storage moduli, relative to commercial BADGE-bas
