The creation of polymer/inorganic (or organic) composite nanoparticles with hydrophobic and hydrophilic surfaces is a very challenging area of research, which is attracting more and more attention. Several approaches utilizing encapsulation technology to create these composite particles will be discussed. One example of encapsulation technology was applied to pigmented inkjet inks as normal dispersants. Inks based on these encapsulated pigment dispersions show a number of advantages, including ink shelf life.
