Abstract
Chocolate milk, paint and snow globes are all examples of solid-liquid suspensions found in daily life. In industry, colloids are also commonly used to process solids, as liquids are typically easier to handle than powders. Given the environmental concerns surrounding the usage of organic solvents, which are often evaporated and released during the process, water-based colloids are preferred. However, not all particles have a natural affinity with water. When particles have insufficient affinity for water, the solid and liquid phases segregate. To enable such particles to still form stable water-based suspensions, their surface properties can be modified....
