High-throughput test platform for adhesion toughness of pressure sensitive adhesives
A novel high-throughput platform for assessing adhesion toughness of pressure sensitive adhesives using a 180-degree peeling test. This method allows simultaneous testing of multiple samples, enabling efficient characterization of adhesion properties.
Overview
This innovative platform offers a high-throughput method to characterize the adhesion toughness of pressure sensitive adhesives (PSAs) through a modified 180-degree peeling test. By employing a linear motor and force sensors, this system enables the simultaneous testing of multiple samples, streamlining the process of assessing adhesion properties. This approach allows for the direct calculation of adhesion toughness from force-displacement data without the need for specific constitutive models, making it applicable to a wide range of adhesive materials.
Technical specifications
Key features:
- Simultaneous testing of multiple adhesive samples under uniform displacement conditions.
- Direct measurement of adhesion toughness from force-displacement curves.
- Adaptable to various adhesive thicknesses and materials.
- Potential to extend testing to include temperature, thickness, and rate dependence.
- Developed using extensive expertise in fracture mechanics and finite element modeling.
Technology readiness level
The platform is currently at Technology Readiness Level 3, indicating experimental proof of concept. Further validation and collaboration with industry partners are sought to refine the testing framework and extend its applications to specific needs, such as flexible or stretchable substrates.
