Toward green three-phase composites with enhanced dielectric permittivity

摘要

This work aims to investigate the dielectric potential of microcrystalline cellulose, a green biosourced material, as a third constituent in the three-phase composites based on ethylene vinyl acetate-vinyl ester of versatic acid (EVA-VeoVa) terpolymer and BaTiO3. For that, new green three-phase composites were prepared using an economic and green process, with simple implementation at room temperature and using water as a solvent. Compared with the binary composite EVA-VeoVa/BaTiO3, the three-phase composite EVA-VeoVa/BaTiO3/microcrystalline cellulose showed an improvement of the BaTiO3 particles dispersion, enhanced relative permittivity, and reduced dielectric loss, which explains the significance of this study.
