Environmental Barrier Coating
What technology is applied to environmental barrier coating via wet processing for the casting process of photo-catalytic titanium dioxide thin films?
Task consigned by the Organization for Small & Medium Enterprises and Regional Innovation, Japan
Titanium dioxide is non-toxic and safe and therefore is used in cosmetics and food additives.
Titanium dioxide films are clear, colorless, elaborately designed and environmentally beneficial.
1. Photo-catalytic films
Photo-catalytic films help increase the dirt resistance of the surfaces of window panes and traffic signs, enhance indoor cooling efficiency and are used also in electronic materials.
2. Photo-catalytic films can cut off ultraviolet rays
Photo-catalytic films help preserve food freshness, provide an anti-fog effect, prevent colors from fading on furniture, and prevent tobacco tar and smell from sticking to furniture.

|
| Thin film coating capability | Capable of thin films of thicknesses in the range of under 100nm (dry) | 0.1 - 3.0µm (wet) | Capable of thin films of thicknesses of 100nm (dry) |
| High-precision coating | ±2% | ±5% | ±2% |
| Speed dependence | Larger coating amount at higher speed | Independent (depends upon pump discharge rates) | Independent (depends upon G-roll rotation frequency and mesh types) |
| Substrate dependence | Low | Not available for thick (tough) substrates | Low |
| Solution dependence | Not available for high-viscosity/high-density solutions | Low | Not good for high-viscosity solutions |
| Others | Affects solution-material compatibility | Available for high-speed coating |
Superiority over existing technologies
Prices for machines for our coating process are one-third of those for vacuum evaporation coating machines, and their power consumption is approximately half that of vacuum coating machines.
| Spray coating | Roll coating | Vacuum evaporation coating | Our coating | |
| Film thickness precision | Poor | Fair | Excellent | Excellent |
| Material cost | Fair | Excellent | Poor | Excellent |
| Facility cost | Excellent | Good | Poor | Excellent |
| Power consumption | Excellent | Excellent | Poor | Excellent |
