High-throughput adhesion measurement with standard lab equipment
A novel method for high-throughput mechanical adhesion measurement using common lab equipment, offering a cost-effective and accessible solution for testing adhesives and coatings.
Overview
Northwestern University presents a cutting-edge method for high-throughput measurement of mechanical adhesion in adhesives and coatings. Developed by Muzhou Wang, this technique addresses the needs for efficient and precise evaluation using commonly-available laboratory equipment. The method streamlines testing by utilizing a standard laboratory centrifuge, multiwell plates, and commercially-available microparticles. It provides both qualitative and quantitative analysis, offering significant potential for research and development in adhesive formulations.
Technical specifications
Key features:
- Utilizes standard laboratory centrifuge, multiwell plates, and microparticles
- Capable of testing multiple adhesive formulations simultaneously
- Provides both qualitative and quantitative adhesion measurements
- Demonstrated quantitative agreement with conventional probe-tack tests
- Specifically effective for pressure-sensitive adhesive formulations
The process involves depositing sample formulations in multiwell plates, adding colored microspheres, and using centrifugation to assess adhesion. Wells retaining particles indicate higher adhesion, while gradual speed increases allow for detailed quantitative analysis.
Technology readiness level
This method is at Technology Readiness Level 6, indicating it is tested in a relevant environment and ready for further commercial application. Its efficacy has been demonstrated in published research, showing alignment with conventional testing methods.
