Introduction
Definition & Key Concepts
Industrial Surface Activity refers to the physicochemical properties of a material’s surface that govern its interactions with other substances. These properties are critical for optimizing:
- Adhesion (coatings, adhesives)
- Lubrication (reducing friction)
- Corrosion Resistance (protective layers)
- Wettability (printing, cleaning processes)
Core Surface Properties
| Property | Description | Measurement Methods |
|---|---|---|
| Surface Area | Total accessible area per unit mass | BET (N₂ adsorption), Gas permeability |
| Porosity | Pore volume/size distribution | Mercury intrusion porosimetry |
| Roughness | Micro/nano-scale texture | AFM, Profilometry |
| Wettability | Contact angle (hydrophilicity/hydrophobicity) | Goniometer |
| Chemical Composition | Functional groups, charge density | XPS, FTIR, SEM-EDS |
Industrial Applications
- Coatings & Paints: Enhanced adhesion via surface roughening or plasma treatment.
- Printing: Controlled ink absorption through porosity modification.
- Medical Devices: Anti-fouling surfaces with hydrophilic coatings.
- Automotive: Low-friction surfaces for engine components.
