Indium Tin Oxide Nanopowder Water Dispersion (ITO, 15-20 nm, 20wt%)

Indium Tin Oxide (ITO) Nanopowder Water Dispersion (ITO, 15-20 nm, 20wt%) is a water-based dispersion containing Indium Tin Oxide (ITO) nanoparticles. ITO is a widely used transparent conductive oxide that is composed of indium oxide (In₂O₃) doped with a small amount of tin oxide (SnO₂). The tin oxide enhances the electrical conductivity of the indium oxide, while maintaining its optical transparency. Below are the key features and technical specifications of this product:

1. Composition and Properties:

• Material: Indium Tin Oxide (ITO), composed of indium oxide doped with tin oxide.
• Concentration (20 wt%): The dispersion contains 20% ITO nanoparticles by weight, with the remaining 80% being water.
• Particle Size: The ITO nanoparticles are in the size range of 15-20 nm, which provides a high surface area and improves the dispersion stability and performance of the material.
• Dispersion Medium: Water-based, making it safer and more environmentally friendly compared to solvent-based dispersions.

2. Key Features:

• Electrical Conductivity: ITO is known for its high electrical conductivity, which is enhanced by the doping of tin oxide. This makes it suitable for applications that require both electrical conductivity and optical transparency.
• Optical Transparency: ITO retains excellent optical transparency, which is essential for transparent conductive coatings and electronic devices that require light to pass through.
• Stable Dispersion: The water-based dispersion ensures that the nanoparticles are uniformly dispersed, which is crucial for consistent performance in applications such as thin films and coatings.

3. Applications:

• Transparent Conductive Coatings: Used for coating materials that need to be both transparent and conductive, such as in displays, touchscreens, solar cells, and smart windows.
• Electrodes for Solar Cells and Displays: ITO is commonly used as a transparent electrode in solar cells, LCDs, and OLEDs, where its conductive and transparent properties are essential.
• Antistatic Coatings: Can be applied to electronic packaging, displays, and other products to prevent the buildup of static electricity.
• Flexible Electronics: Used in flexible electronics, such as wearable devices and bendable touchscreens, due to its excellent conductivity and transparency combined with flexibility.

4. Advantages:

• High Electrical Conductivity and Transparency: Offers a unique combination of conductivity and optical transparency, making it ideal for applications where both properties are essential.
• Environmentally Friendly: The water-based formulation is safer to handle and more environmentally friendly compared to solvent-based dispersions.
• Easy to Handle and Apply: The dispersion is stable, which makes it easier to use in various applications like thin-film coatings, providing a uniform application.

5. Handling and Storage:

• Storage: Store in a cool, dry place, and ensure the container is sealed tightly to prevent evaporation or contamination.
• Safety: While ITO nanoparticles are generally safe, it’s important to handle the dispersion with care and follow appropriate safety procedures, including using personal protective equipment (PPE) such as gloves and goggles.

Summary:

Indium Tin Oxide (ITO) Nanopowder Water Dispersion (ITO, 15-20 nm, 20wt%) is a water-based dispersion that contains ITO nanoparticles with a 15-20 nm particle size and a 20% concentration. It provides excellent electrical conductivity and optical transparency, making it ideal for transparent conductive coatings, solar cells, touchscreens, and flexible electronics. The water-based formulation ensures ease of handling and is environmentally friendly compared to solvent-based dispersions.
