のである。On the other hand, synthetic polymer compounds such as polypinylidene fluoride, polyvinyl chloride, polyvinyl fluoride, and nylon are also known to have piezostatic properties. These piezoelectric polymer compounds have many features such as excellent workability and formability that ceramics do not have, and can be used in film form, so they are used in speakers, headphones, microphones, and ultrasonic probes. Although it is expected to be used in many fields such as keyboards, blood pressure monitors, etc., it has drawbacks such as a high polarization voltage and a small piezoelectric constant. In order to solve these problems, in recent years, so-called piezoelectric polymer composite materials, in which ceramic fine particles such as lead titanate particles and PZT particles are mixed with a piezoelectric polymer compound, have been actively developed. Like piezoelectric polymer compounds, these composite materials also have excellent moldability and processability, and have a suitable degree of plasticity, and can be formed into a film, making them extremely versatile materials. By combining the ceramic particles and the piezoelectric polymer compound, the piezoelectric constant became several times larger and the polarization voltage was considerably lowered. However, since the polarization voltage is still considerably higher than that of ceramic piezoelectric materials, it is currently quite difficult to polarize thick materials. The present invention provides a method for producing a piezoelectric polymer composite material comprising lead titanate particles and a piezoelectric polymer compound, which has a lower polarization voltage than conventional materials.

Ｚ線法が用いられる。That is, the present invention aims to provide a method for manufacturing a composite material that can obtain a large piezoelectric constant when the same polarization voltage is applied to the materials having the same thickness. The present invention focuses on lead titanate particles, which are one of the components of a composite material, and have a plate-like shape with a developed C-plane. Conventionally, it has been difficult to produce lead titanate particles that have a plate-like or needle-like shape because the titanium dioxide and lead compounds that are the starting materials for lead titanate particles do not have a specific shape. Ta. However, titanium tetrachloride (T
Titanium dioxide particles having an anatase type crystal structure having a plate-like shape can be obtained by a so-called gas phase method in which a mixed gas consisting of ICZ4 )-oxygen (02)-nitrogen (N2) is reacted at high temperature. This titanium dioxide powder is mixed with lead oxide or a lead compound that becomes lead oxide when heated.
By firing, as shown in FIG. 1, plate-shaped lead titanate particles with developed C-planes are obtained. The polarization processing voltage of a composite material made by mixing such particles with a piezoelectric polymer compound such as polyvinylidene fluoride and forming it is lower than that of a conventional composite material using lead titanate particles that do not have a specific shape. It was found that polarization can be achieved simply by applying a voltage. When producing piezoelectric polymer composite materials, the mixed Z-ray method is often used.

以下、本発明の実施例について詳細に説明する。According to this method, lead titanate particles having a plate-like shape are in-plane oriented within a piezoelectric polymer material by pressure molding. Due to distribution assimilation, there is a second layer in the thickness direction of the sheet.
As shown in the figure, the plate surfaces of the lead titanate particles are aligned. FIG. 2 shows the arrangement of particles in two piezoelectric polymer materials, and the C-axis direction is aligned in the thickness direction of the sheet. A composite material is produced in which a plane perpendicular to the C axis, that is, a C plane is arranged in a certain plane. In other words, when such a composite material is subjected to polarization 2 treatment in the thickness direction of the sheet, the axial direction of the particles is disordered when lead titanate particles without a specific shape are used, whereas the axial direction of the particles is disordered. In the composite material according to the invention, since the C-axes of the particles are aligned in the thickness direction of the sheet, polarization becomes easy and polarization is possible with a low applied voltage. That is, when sheets of the same thickness are treated with the same polarization voltage, it is possible to obtain a large piezoelectric constant.
Examples of the present invention will be described in detail below.

。Gold was vapor-deposited on both sides of this film, and electrodes were provided to polarize it. The polarization conditions are: DC voltage between 3 powders in 9000~50~
A voltage of 120 kV was applied and the temperature was gradually lowered to room temperature. FIG. 3 shows the results of measuring the piezoelectric constant d of the polarized composite material. For comparison, we measured the piezoelectric constant d3 after mixing and molding a conventional composite material using lead titanate particles that do not have a specific shape and subjecting it to polarization treatment under exactly the same conditions. is similarly shown in FIG. Here, the solid line shows the characteristics of the present invention, and the broken line shows the characteristics of the conventional one. As is clear from FIG. 3, the polarization treatment voltage of the composite material according to the present invention is lower than that of the conventional material.
Furthermore, as a result of performing X-ray diffraction measurements on the composite material according to the present invention and the conventional composite material after molding, it was found that the former had a higher
The value of (OO)/21(HK) was large, and it was confirmed that the plate-shaped lead titanate particles with C-planes developed in the thickness direction of the sheet were oriented in-plane. However, Z1 (oo so) indicates the sum of peak intensities of the (oo so) plane, and 21 (hk so) indicates the sum of all peak intensities. As is clear from the above results, the piezoelectric polymer composite material according to the present invention, which is formed by mixing and molding lead titanate particles having a plate-like shape with a developed C-plane and a piezoelectric polymer compound, has not been used conventionally. Compared to composite materials made of lead titanate particles that do not have a specific shape, polarization can be achieved with a lower applied voltage, productivity is improved, and the industrial value thereof is extremely large.
