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
