Contact Angle Analyzer
Purpose
The Contact Angle Analyzer skill provides comprehensive wettability analysis for nanomaterial surfaces, enabling determination of surface energy components and characterization of hydrophobic/hydrophilic properties.
Capabilities
- Static contact angle measurement
- Dynamic advancing/receding angles
- Surface energy calculation (Owens-Wendt, van Oss)
- Wilhelmy plate analysis
- Surface roughness correlation
- Superhydrophobic/superhydrophilic assessment
Usage Guidelines
Wettability Analysis
- Contact Angle Measurement
- Use consistent droplet volume (2-5 uL)
- Allow equilibration before measurement
- Report average of multiple measurements
- Surface Energy Calculation
- Use multiple probe liquids
- Apply Owens-Wendt for dispersive/polar
- Use van Oss for acid-base analysis
- Surface Classification
- Hydrophilic: theta < 90 degrees
- Hydrophobic: theta > 90 degrees
- Superhydrophobic: theta > 150 degrees
Process Integration
- Nanomaterial Surface Functionalization Pipeline
- Thin Film Deposition Process Optimization
