Superhydrophobic Surface Coating via Nanoparticle Deposition ID: 2012-058

A novel method for creating superhydrophobic surfaces on touch screens, making them self-cleaning through a one-step nanoparticle deposition process.

Technology Overview

This technology involves a unique one-step deposition process using urea-formaldehyde polymer to deposit nanoparticles onto a substrate, which is then subjected to high-temperature treatment. This treatment removes the polymer and strengthens the nanoparticle coating. The surface is finally treated chemically with a hydrophobic agent, such as perfluorosilane, to achieve exceptional water and oil repellency. The method is distinguished by its simplicity and effectiveness in creating durable, superhydrophobic surfaces.

Key Advantages

• One-step deposition process simplifies the coating procedure
• High-temperature treatment enhances the mechanical stability of the coating
• Chemical treatment with hydrophobic chemicals ensures high water and oil repellency
• Potential for improved transparency and durability of touch screen surfaces

Problems Addressed

• Complexity and inefficiency in creating superhydrophobic surfaces
• Lack of durability and mechanical stability in existing hydrophobic coatings
• Difficulty in maintaining cleanliness and clarity of touch screen surfaces

Market Applications

• Self-cleaning touch screens for smartphones, tablets, and interactive displays
• Protective coatings for outdoor displays and digital signage
• Advanced water and oil repellent surfaces for optical devices and sensors
