Description

<p>The dispersion of self-assembled BaTiO3 (BT) agglomerates in poly-L-lactic-acid (PLLA) polymer matrix was decided with the multifractal analysis to investigate characters of the aggregated morphology of the secondary particle group. On the multifractal analysis, the results showed that the average secondary particle area is increased with increasing the capacity dimension (D0). The average secondary particle area is related to BT agglomerates. It showed that S1/2 and D0 plot increased linearity. Therefore, BT agglomerates and D0 have a correlation. It suggested that D0 is related to the morphology of the BT agglomerates. The average dielectric constant (ε′) is increased with increasing D0. It was considered that the formation of the hetero interface of BT/PLLA contributed to the increase in the average dielectric constant of BT/PLLA composites.</p>
