🔬 Applications (in Detail)
1. Transparent Conductive Coatings (TCO)
ATO is widely used as a transparent conductive oxide in displays, touch panels, and LCDs.
Provides visible transparency (>80%) with low sheet resistance.
Suitable for anti-static and EMI-shielding coatings on glass or plastic substrates.
2. Infrared (IR) Shielding & Heat Control Films
Strong IR reflection and absorption properties make ATO ideal for heat-insulating coatings.
Used in automotive windows, architectural glass, and energy-saving films.
Blocks IR radiation while maintaining high visible light transmission.
3. Antistatic & EMI Shielding Applications
ATO nanoparticles impart antistatic properties to plastics, coatings, and fabrics.
Prevents static buildup in electronic packaging, optical lenses, and touch displays.
Used in EMI shielding paints and conductive polymers.
4. Photocatalysis & Sensors
Doped SnO₂ structure enhances photoelectrical and gas-sensing properties.
Used in gas sensors, photocatalytic degradation of pollutants, and UV detectors.
5. Solar and Optoelectronic Devices
Acts as a transparent electrode in solar cells, electrochromic devices, and OLEDs.
Enhances light management, conductivity, and device lifetime.
6. Paints & Coatings
Used as a nano-additive in antistatic paints, transparent conductive coatings, and UV-blocking finishes.
Provides durability, chemical resistance, and thermal stability.
7. Polymer & Textile Applications
Imparts conductivity and UV/IR shielding in synthetic fibers and plastic films.
Used for smart textiles, anti-dust fabrics, and flexible electronics.
⚠️ Handling & Storage
Store in a cool, dry place away from humidity and strong oxidizing agents.
Handle under inert atmosphere if possible.
Use gloves, masks, and eye protection to avoid nanoparticle inhalation or skin contact.
