A tunable method for generating non-fading printed structural color is demonstrated. The process involves the rapid generation and self-assembly of particle strings, using standard colloidal polymeric particles and AC electric fields, with no requirement for a “wash-out” step. By using an organic UV-curable medium, we demonstrate that these tunable structures can be permanently fixed in a flexible polymer matrix and thus are suitable for printing applications.
