Superhydrophobic and photocatalytic self-cleaning coating for toilets
Innovative coating combining superhydrophobic and photocatalytic properties to enhance toilet cleanliness, reduce grime buildup, and lower water usage. Ideal for high-frequency environments with long-term stability and resistance.
Overview
The superhydrophobic and photocatalytic self-cleaning coating is designed to revolutionize the cleanliness and maintenance of toilets. By integrating superhydrophobic properties with titanium dioxide's photocatalytic capabilities, this coating significantly reduces urine and feces adhesion, minimizing grime buildup and enhancing overall hygiene. The result is a cleaner, more efficient toilet that requires less water and manual cleaning.
Technical specifications
Key features:
- Superhydrophobic properties: Achieves a contact angle exceeding 150°, resulting in liquids forming spherical droplets that roll off surfaces, reducing adhesion.
- Photocatalytic action: Utilizes titanium dioxide to generate reactive free radicals that decompose organic matter, inhibit bacterial growth, and prevent odors.
- Durability: Designed to withstand high-frequency use with excellent wear and corrosion resistance.
The coating is composed of silica and titanium dioxide particles, modified with polydimethylsiloxane (PDMS), enhancing both water repellency and organic contaminant degradation.
Technology readiness level
This technology is at TRL 4, having been validated in laboratory settings. Ongoing efforts include testing contact angles, adhesion to artificial excrement, antibacterial properties, and biodegradability over a one-year period. Partnerships are sought to advance development, including material access, testing equipment, and funding.
