The aim of this work was to realize and mechanically characterize composites based on poly(butyleneadipate-terephthalate) (PBAT) filled with micrometric particles of zein-TiO2 complex (ZTC) at different concentrations.

Abstract
The aim of this work was to realize and mechanically characterize composites based on poly(butyleneadipate-terephthalate) (PBAT) filled with micrometric particles of zein-TiO2 complex (ZTC) at different concentrations. Specimens model 1BA were obtained by injection molding and subjected to a uniaxial tensile test (UTT). The addition of the ZTC proved to have a reinforcing effect on the matrix, an increase in both Young’s modulus (E) and yield stress (σy) being observed. The mechanical properties were modeled applying Kerner’s and Pukánszky’s models, obtaining a good correspondence between theoretical experimental values and good matrix-filler interfacial interaction, respectively. Microscopical analysis revealed a good dispersion of the filler within the matrix.File | Dimensione | Formato | |
