Multidisciplinary adhesion modeling using CA, AFM, and SEM-RAMAN techniques
A comprehensive adhesion analysis model integrating CA wettability, AFM tribology, and FESEM-RAMAN imaging to investigate molecular interactions and material compositions for applications in biomedical devices, electronics, and more.
Overview
This innovative adhesion modeling approach integrates multiple advanced techniques to provide a comprehensive analysis of adhesion properties critical for various industries such as biomedical devices, electronics, and cultural heritage preservation. By combining contact angle (CA) measurements, atomic force microscopy (AFM) with liquid injection tips, and high-resolution field emission scanning electron microscopy (FESEM) with energy-dispersive X-ray spectroscopy (EDS) and Raman imaging, this model offers unparalleled insight into the chemical, physical, and tribological aspects of surface adhesion.
Technical specifications
Key components of the approach include:
- Contact Angle (CA) Measurements: Assesses surface wettability and surface energy through static, dynamic, and sliding contact angles.
- Atomic Force Microscopy (AFM): Utilizes liquid injection tips for localized adhesive application and measures nanoscale forces and interaction at the molecular level.
- FESEM-EDS-Raman Imaging: Provides ultra high-resolution images for morphological analysis, elemental composition assessment, and molecular characterization through Raman spectroscopy.
- This multidisciplinary method generates a detailed chemical-physical-tribological dataset crucial for developing adaptive models applicable to new material combinations.
Technology readiness level
The technology is currently at Technology Readiness Level 3, indicating that the experimental proof of concept has been demonstrated through a multi-technique approach. Future validation will further refine the model, focusing on surface preparation, contact angle measurements, surface tension analysis, and nanoscale adhesion force assessments.
About Consiglio Nazionale delle Ricerche
Consiglio Nazionale delle Ricerche (CNR) is Italy’s national public research organization, operating at scale through a distributed network with broad, mission‑driven R&D. Its institutes are embedded across major regions, often co‑located with universities, hospitals, and industrial districts, enabling rapid collaboration, access to specialized facilities, and contract research. Company engagement is streamlined via liaison offices that arrange sponsored work, joint labs, secondments, and access to shared infrastructure and pilot sites. CNR’s programs are backed by competitive funding from European Commission initiatives and Italian national ministries. A centralized technology transfer office manages IP, licensing, and startup formation for industry partners.
