Microencapsulation

Microencapsulation is the process of creating small spheres which contain droplets of an internal phase and due to its versatility can be used to provide a stable method of packaging and protecting many materials including liquid crystal and leuco dye products. These spheres can range from sub-micron to ~1mm in size depending on the process they are to be used in.

The process is normally performed in a water phase which gives slurries of capsules suspended in water. This water can be evaporated off using processes such as spray drying to give a powder which can be used in other non-aqueous systems and can even be added to plastics in some cases.
