Researchers from the PECMAT and CMP teams have shown [R. Szweda et al. Angew. Chem. 2018] that digital information can be organized in three dimensions through thin multilayers (millefeuille) of polymers. They synthesized coded polyelectrolytes containing definite sequences of monomers, in which a binary message can be written. These molecules were deposited by layer-by-layer techniques. Using a library of 16 different polymers, they succeeded in inserting a quote from the French chemist Marcellin Berthelot into this millefeuille. These new materials are promising for applications in the field of data storage but also for anti-counterfeiting technologies.
