“…This is similar to the agglomeration/aggregation and growth of fillers in a matrix. As previously reported for fractal material texture organization, [6][7][8][9][10][11][12][13][14][15] the construction of this self-assembly/self-organization consists of the following two processes:…”

“…In particular, the interaction of the filler particles in the matrix and the resulting network formation are important for expressing specific functionality. In fact, in β-Si 3 N 4 (SN)/austenitic stainless steel (SUS) [6,7] and BaTiO 3 (BT)/piezoelectric polyvinylidene fluoride (PVDF) [8][9][10][11][12][13][14][15] systems, the characteristics of the material structure constructed by the process of self-assembly or self-organization have been mapped to material performance such as dielectric properties and thermal conductivity.…”

To investigate the relationship between histological properties and thermal conductivities of binary self-assembled/self-organized fractal materials fabricated by the mixed diffusion of filler particles, the particle group distribution of the filler particles was analyzed. Unlike conventional research on particle size distribution, we performed an analysis that focuses on interactions and connectivity between particles from the perspective of the Barabasi-Albert model. In three complex network systems of β-Si3N4 (SN)/austenitic stainless steel (SUS), SN/piezoelectric polyvinylidene fluoride (PVDF), and BaTiO3 (BT)/PVDF, the size distribution of secondary particles was a power-law distribution until the particle group grew relatively large. In the SN/SUS and SN/PVDF systems, a crossover phenomenon was observed in which the order distribution exhibited a power-law in the region where the particle group area was small, and as the particle group became larger, the order distribution became exponential distribution. On the other hand, the BT/PVDF system deviated from the power law distribution as the particle group area increased but did not exhibit an exponential distribution. The characteristics of the particle group distribution of these filler particles were closely related to thermal conductivity, indicating that the connection of particle groups was important. Furthermore, the relationship between the multifractal capacitance dimension, which is strongly correlated with the distance between the particle groups, and the total number of filler particle groups suggests that the texture of these composite material systems may have both small-world and scale-free properties. We also focused on the relationship between the multifractal and complex network properties of the three particle groups. As a result, a correlation was found between the slope γ, which reflects the characteristics of the power distribution, and the thermodynamic parameter α (corresponding to internal energy change) obtained from multifractals. In particular, the smaller the change in γ relative to the change in α, the more pronounced the bonding of particles and particle groups, while the larger change in γ suggested the dispersion of particle groups.

“…2) On the other hand, BT is one of the main lead-free electronics for dielectric, piezoelectric, and electro-optic applications. 2) Meanwhile, an example of using a polymer material with dielectric properties was provided in a previous report, 3) in which a polymer piezoelectric biosensor with a polyvinylidene fluoride (PVDF) was proposed. In this report, we proposed that it is possible to detect biopolymers using the adsorption characteristics of the hostguest reaction on the sensor via the relaxation behavior of the ¢-PVDF piezoelectric material.…”

“…In this report, we proposed that it is possible to detect biopolymers using the adsorption characteristics of the hostguest reaction on the sensor via the relaxation behavior of the ¢-PVDF piezoelectric material. 3) However, ¢-PVDF has a significantly lower elastic constant than quartz, which is a signal transducer sensor of a general biosensor for mass detection. Therefore, the shear vibration of ¢-PVDF was affected by the solution viscosity, which, in turn, affected the change in the ¾B of ¢-PVDF.…”

“…Therefore, the shear vibration of ¢-PVDF was affected by the solution viscosity, which, in turn, affected the change in the ¾B of ¢-PVDF. 3) Hence, it is expected that it is possible to control the shear vibration by adding ceramic fillers to PVDF. In this paper, the BT/PVDF composites materials were manufactured as an application of BT.…”

In this paper, the properties of the barium titanate (BT)/polyvinylidene fluoride (PVDF) composites were controlled by the self-assembly of the BT secondary particle groups. The self-assembled BT/PVDF composites of 520 vol.% BT were prepared with the difference in the viscosity of polyethylene glycol (PEG) of dispersants involved in the self-assembly process. The multifractal properties and dielectric properties of the self-assembled BT/PVDF composites were investigated with controlling by the formation of the self-assembled BT secondary particle groups. The dielectric constant (¾¤) increased with an increase in the average secondary particle area (S) of the BT particles. The S increased with an increase in the viscosity of PEG; whereas, the ¾¤ decreased with the increase in viscosity. The multifractal analysis indicated that the distribution of self-assembled BT secondary particle groups was affected by PEG viscosity. The sample with PEG1000 had aggregates with a BT/PVDF/BT heterointerface, the sample with PEG20000 had agglomerates with a BT/BT interface, and the sample with PEG2000 had both, aggregates and agglomerates. The BT/PVDF/BT heterointerface in the BT aggregates played an important role in improving the dielectric properties of the BT/PVDF composites. Overall, the viscosity of the dispersant affected the self-assembly process as well as the ¾¤. It was suggested that the multifractal properties and dielectric properties were controlled by the self-assembly of the BT secondary particle groups.
