High-throughput adhesion characterization using pressurized interfacial failure
A pressurized interfacial failure (PIF) method for high-throughput, precise adhesion characterization. By combining force and pressure measurements, PIF quantifies adhesion and derives key material properties such as interfacial strain energy release rate and elastic modulus. The approach includes an automated 48-sample testing array, adaptable sample mounting designs, Python-based data analysis software, and integration with automated sampling equipment, with validation demonstrated for pressure-sensitive adhesives.
Overview
The pressurized interfacial failure (PIF) method provides adhesion characterization by combining force and pressure measurements to quantify adhesion and assess material properties. The method is designed to support high-throughput testing and precise performance assessment across a broad range of materials. Validation has been demonstrated for pressure-sensitive adhesives (PSA), with further expansion of applications supported by ongoing development.
Technical specifications
The PIF method uses an annular probe to create an interface between materials. Fluid is compressed within the probe to pressurize the interface, inducing radial cavity expansion. This process enables calculation of critical material properties, including the interfacial strain energy release rate and elastic modulus. Proposed enhancements include:
- Automated 48-sample testing array for high-throughput evaluations
- Advanced sample mounting designs to accommodate diverse materials and conditions
- Python-based data analysis software for comprehensive analysis and visualization
- Integration with automated sampling equipment
Technology readiness level
The PIF method is currently at Technology Readiness Level 5, with validation demonstrated for specific materials such as PSA. Ongoing advancements include prototype sample mounts, automated equipment integration, and software development to refine and expand the method’s capabilities and improve testing efficiency.
