TiO₂ Nanoparticles for Antibacterial Coatings
The Power of Nanoscale Protection
As microbial resistance increases and the demand for safer environments grows, antibacterial coatings are becoming essential across healthcare, industrial, and consumer sectors.
At the forefront of this innovation is Titanium Dioxide (TiO₂) in its nano-form.
Schnaiffer's TiO₂ nanoparticles offer a potent, durable, and scalable solution to antibacterial surface technology.
What Are TiO₂ Nanoparticles?
TiO₂ nanoparticles are ultra-fine particles of titanium dioxide, typically less than 100 nm in size.
Our nanoparticles are synthesized via a controlled sol–gel process using high-purity Titanium (IV) Tetra-Isopropoxide (TTIP), acetic acid, and deionized water under low-temperature conditions.
The resulting nanocrystalline TiO₂ thin films exhibit excellent uniformity, high purity, and strong adhesion to substrates like oxidized silicon or glass.
Why Use TiO₂ Nanoparticles in Antibacterial Coatings?
1. Photocatalytic Antimicrobial Action
- Generates reactive oxygen species (ROS) under UV or visible light.
- Disrupts microbial cell membranes and DNA, ensuring thorough disinfection.
2. Nanofilm Uniformity
- Sol–gel derived particles create thin, even coatings with high surface reactivity.
- Ideal for transparent and hydrophilic surfaces.
3. Long-Term Durability
- Stable in harsh environments and repeated cleaning cycles.
- High crystallinity ensures retained efficacy over time.
4. Environmentally Safe & Biocompatible
- Free from toxic metal additives.
- Safe for food contact and skin-exposed applications.
5. Surface Adaptability
- Bonds well with glass, silicon, ceramic, and select polymers.
- Compatible with roll-to-roll, dip, and spray coating methods.
