Non-adhesive superhydrophobic surface treatment for foam curing
Introducing a femtosecond laser-processed superhydrophobic surface that prevents polymer adhesion, ideal for foam curing applications, offering self-cleaning and anti-scratching benefits.
Overview
The University of Rochester presents an innovative non-adhesive superhydrophobic surface treatment designed for foam curing applications. Utilizing advanced femtosecond laser processing technology, this solution offers a self-cleaning, anti-staining, and anti-scratching surface that significantly reduces polymer adhesion. This is particularly beneficial for industries that require high-fidelity thermal printing of superhydrophobic polymer surfaces, as our technology allows for repeated use of metal molds without degradation.
Technical specifications
Key features:
- Femtosecond laser processing: Enables the creation of non-adhesive, superhydrophobic surfaces without the need for coatings.
- Durable and reusable molds: Allows metal molds to be reused over 50 times, maintaining high fidelity in printing processes.
- Versatile compatibility: Suitable for treating various metal surfaces used in foam curing applications.
- Self-cleaning properties: Reduces maintenance and enhances the longevity of molds.
- Anti-staining and anti-scratching: Extends the lifespan of molds and improves product quality.
Technology readiness level
Currently, this technology is at TRL 2, indicating that the basic principles have been observed and reported. The focus is on optimizing laser processing parameters to enhance the anti-sticking properties on customer-specific mold materials, using the contact angle of liquid polyisocyanurate at elevated temperatures as a feedback mechanism for refinement.
