Dielectric materials are electrical insulation materials that can store charges. The dielectric constant is an important performance indicator of dielectric materials, used to measure the response of materials to charge storage capacity in an electric field. The dielectric constant is divided into two types: relative dielectric constant and absolute dielectric constant, among which the relative dielectric constant is commonly used in the study of dielectric materials. There are many commonly used dielectric materials, including:
1. Oxides: nano barium titanate (BaTiO3), nano titanium dioxide (TiO2), alumina (Al2O3), etc;
Example: Barium Titanate (BaTiO3): Barium Titanate is a high-performance and widely used ferroelectric ceramic
Ceramic materials can be used for polymer modification to improve the dielectric constant of materials. It is also widely used in the fields of capacitors, ceramic piezoelectric materials, sensors, etc.
The dielectric constant of epoxy resin is relatively low (about 3-4), and filling epoxy resin with nano BaTiO3 can significantly improve its dielectric constant.
Adding BaTiO3 to epoxy resin resulted in a composite material with a dielectric constant of around 50. The size of filler particles, type and dosage of coupling agent have a significant impact on the dielectric properties.
Example: Titanium Dioxide (TiO2): TiO2 is a widely used material with excellent photocatalytic, optoelectronic, and charge transfer properties. Its high dielectric constant (about 200) makes it widely used in electronic devices, solar cells, and optoelectronic devices.
2. Polymers: polytetrafluoroethylene (PTFE), polypropylene (PP), polyethylene (PE), etc;
3. Ceramics: iron oxide (Fe2O3), strontium silicate (SrTiO3), zirconia (ZrO2), etc. In dielectric materials, the addition of nanoparticles can significantly increase the dielectric constant of the material. Dongguan SAT NANO New Materials Company provides high-quality products such as nano metal powder, oxide powder, carbide powder, alloy powder, etc. The addition of these nano materials can effectively improve the performance of dielectric materials. For example, adding nano barium titanate to epoxy resin can yield a dielectric constant of around 50.
The influence of composite materials, filler particle size, coupling agent type and dosage on dielectric properties is significant. In addition, nano titanium dioxide is also a material with excellent dielectric properties and wide applications, which can be used to prepare high-performance capacitors, sensors and other equipment.
In short, there are various types of dielectric materials, and different materials have different dielectric constants and performance characteristics. In practical applications, selection and processing need to be based on specific requirements. And the high-quality nanomaterials provided by Dongguan SAT NANO New Materials Company can provide various
The application of dielectric materials in the industry provides support, providing an effective way to achieve high-performance and low-cost goals.
