Resveratrol/POSS-based polymethacrylates for DLP 3D printing and fluorescent anti-counterfeiting

A trifunctional methacrylate monomer (REM) was synthesized from biomass resveratrol to address the need for sustainable resins in digital light processing (DLP) 3D printing. The polymer properties were optimized by incorporating methacryloxypropyl polyhedral oligomeric silsesquioxane (MA-POSS) with different mass fractions. Light-curing biobased materials (REM/POSS) exhibited enhanced thermal stability and dielectric properties. The REM/POSS-30 % composite showed a low dielectric constant ( D k  = 2.90 at 14.2 GHz) and excellent thermal stability. Compared to commercial bisphenol A-based resins (MEP), REM/POSS-0 % demonstrated superior comprehensive performance. The stilbene structure of resveratrol in REM/POSS polymers provided strong blue fluorescence under UV light, suggesting potential for information storage and encryption. The successful fabrication of complex structures confirmed the compatibility of REM/POSS with DLP 3D printing, offering a promising alternative to petroleum-based materials in both 3D printing and anti-counterfeiting applications.
