Indium Tin Oxide Nanopowder Water Dispersion (ITO, In₂O₃:SnO₂ = 95:5, 99.99%, 20-70 nm, 20wt%) is a water-based dispersion containing high-purity Indium Tin Oxide (ITO) nanoparticles. The material is optimized for applications requiring a balance of high electrical conductivity and optical transparency. Below are the detailed specifications and characteristics of this product:
1. Composition and Properties:
- Material: Indium Tin Oxide (ITO), with a composition ratio of 95% indium oxide (In₂O₃) to 5% tin oxide (SnO₂). This ratio is commonly used to achieve a higher conductivity while maintaining adequate transparency for specific applications.
- Purity: The 99.99% purity indicates a high level of material quality with minimal impurities, ensuring enhanced performance in sensitive applications.
- Particle Size: The ITO nanoparticles in this dispersion have a size range of 20-70 nm, which strikes a balance between high surface area and dispersion stability.
- Concentration: The dispersion contains 20% ITO nanoparticles by weight, with the remaining 80% being water. This concentration is typically chosen for applications requiring stable dispersions that can be easily applied in thin films or coatings.
2. Key Features:
- Electrical Conductivity: ITO is known for its excellent electrical conductivity, which is further enhanced by the tin oxide (SnO₂) dopant. The higher indium content (95%) in this formulation provides better conductivity compared to other compositions with lower indium content.
- Optical Transparency: Despite its high conductivity, ITO retains significant optical transparency, making it an ideal material for transparent conductive films where both transparency and conductivity are needed.
- High Purity: The 99.99% purity ensures minimal contaminants, resulting in consistent performance in demanding applications.
- Stable Water Dispersion: The water-based formulation ensures that the nanoparticles are uniformly dispersed, which is important for thin film deposition and coating processes.
3. Applications:
- Transparent Conductive Coatings: ITO is widely used for transparent conductive coatings in various electronic devices like displays, touchscreens, solar cells, and smart windows where both electrical conductivity and transparency are essential.
- Electrodes in Solar Cells and Displays: Used as transparent electrodes in solar cells, OLEDs, LCDs, and touchscreen displays. The high conductivity and transparency make ITO a go-to material for these technologies.
- Flexible Electronics: This dispersion is suitable for use in flexible electronics like wearable devices and bendable displays, where both transparency and conductivity are required without compromising flexibility.
- Antistatic Coatings: Used for antistatic coatings in electronic packaging and other devices to prevent the buildup of static electricity.
- Optical Coatings: In applications like optical sensors, photodetectors, and transparent electrodes in photovoltaics or other optical devices where a combination of electrical conductivity and transparency is required.
4. Advantages:
- Excellent Electrical and Optical Properties: ITO nanoparticles provide a high combination of electrical conductivity and optical transparency, making it ideal for transparent electronics and energy harvesting technologies such as solar cells.
- High Purity: The 99.99% purity ensures minimal impurities, leading to improved performance and stability in sensitive applications.
- Environmentally Friendly: The water-based dispersion is safer and more environmentally friendly compared to solvent-based dispersions.
- Easy to Use and Apply: The dispersion is designed for uniform application in various thin-film deposition and coating techniques, making it ideal for manufacturing processes.
5. Handling and Storage:
- Storage: The dispersion should be stored in a cool, dry place with the container tightly sealed to prevent evaporation of the water and contamination.
- Handling: Personal protective equipment (PPE) such as gloves and safety goggles should be worn when handling the dispersion to avoid direct contact with nanoparticles.
- Safety: While ITO nanoparticles are generally safe, it is important to follow safety guidelines to minimize inhalation or skin exposure, especially in larger-scale handling.
