Several factors can influence colloidal stability, including:
- Particle Size: Smaller particles have higher surface energy, making them more prone to aggregation. - Surface Charge: Electrostatic repulsion between similarly charged particles can prevent aggregation. - pH: The pH of the medium can affect the surface charge and, consequently, the stability. - Ionic Strength: High ionic strength can screen the electrostatic interactions, leading to aggregation. - Temperature: Changes in temperature can affect the kinetic energy of the particles, influencing their stability.
