Effect of ceramics/polymer heterointerface on dielectric property of self-assembled BaTiO<sub>3</sub>/poly-L-lactic acid composite materials

The dispersion state of barium titanate (BT) particle groups in self-assembled BT/poly-L-lactic-acid (PLLA) composites prepared under different fabrication conditions was investigated. In particular, the BT/PLLA/BT heterointerface BT aggregates by self-assembly process analyzed and effect BT/BT interface on dielectric properties BT/PLLA were fabricated adding particles granules with low high-speed kneading conditions. volume fraction varied from 5 to 20 vol.%. having a formed low-speed condition agglomerates within process. tan δ composite lower than that interface. constant (ε′) increased growing an average secondary area fillers. contrast, increased, as compared vol.% BT. However, change ε′ saturated. slopes depending fillers between Thus, it suggested important role improving form ceramic ceramics/polymer/ceramics
