Utilisation de cellulose pour l'élaboration de matériaux photoluminescents ou conducteurs

Abstract : The context of this project is the cellulosic material functionalization in the printed electronic domain. The first part highlighted the ability to print photoluminescent formulations. The aqueous dispersion was composed of semiconducting polymer nanoparticles. The influence of the size and the composition of the particles on the emission colour was studied. Security paper is one of the main potential application of these particles. The second part dealed with the use of cellulose microfibrills and copper microparticles for the elaboration of conductive composite films. The films were self-supporting thanks to the high mechanical properties of the microfibrills. A calendering study was carried out on the electric conductivity of the films based on the influence of the pressure and the temperature of calendering.
