Abstract
Barium titanate (BT) and microcrystalline cellulose (MCC) were used to improve the dielectric properties of a commercial vinylic resin. Using a green method, two binary composites (vinylic resin/BaTiO₃, vinylic resin/MCC) and one ternary composite (vinylic resin/BaTiO₃/MCC) were prepared. The results obtained for the MCC containing composite show an identical evolution of the relative permittivity compared to BaTiO3 composites with weak dielectric losses. In consequence, the feasibility of the substitution of BaTiO3 with MCC, an economical and biosourced material is demonstrated.
