Amidst the escalating energy demand, development of nonfossil, biorenewable, and sustainable resources becomes particularly pressing crucial. In this research, a biomass polyurethane acrylate (JPUA) derived from jatropha oil (JO) was successfully synthesized JPUAx composite coating fabricated by doping monolayer graphene (LG) nanoparticles. After rapid UV curing, has twice mechanical properties JPUA coatings, with tensile strengths up to 15.8 MPa, significant advantage over other coatings type, as well excellent corrosion resistance. The immersed in strong acid, alkali, high-salt solutions for 30 days negligible changes quality or surface morphology. Based on outstanding resistance JPUAx, fluorescent biobased prepared loading powders different colors, dual anti-counterfeiting system constructed combining Morse code. Fluorescent stickers have also been developed facilitate long-term encryption daily life. Overall, work not only expands synthesis strategy polymers nonfossil but provides an additional way multifunctional information applications.

ABSTRACT Designing and preparing bio‐based epoxy monomers to substitute hazardous nonrenewable bisphenol A (BPA)‐type epoxide are important for the development of new resins under concept healthy sustainable concept. In this work, a “green” bifunctionality monomer derived from eugenol (EGE‐EP) was fabricated by epoxidation functionalization unsaturated double bond as well using epichlorohydrin epoxidize phenolic hydroxyl group. The effects different hardeners on properties EGE‐EP were analyzed, E51 cured with same employed reference. results indicate that EGE‐EP/hardeners present desired curing behavior, mechanical performances, thermal stability which comparable commercial E51/hardeners resin. Most importantly, all EP/hardeners samples exhibit lower onset temperature compared systems reflecting faster mixtures. Meanwhile, an obvious improvement char yield is found in contrast thus possessing potential flame retardancy applications. This study proposes innovative path prepare alternative BPA‐type epoxide, significance eco‐friendly high‐value utilization biomass.
