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