Abstract
A pigment-based ink is disclosed. The ink includes a non-polar carrier fluid and a nitrogen-linked surface functionalized pigment particle, wherein the nitrogen-linked surface functionalized pigment particle is suspended in the non-polar carrier fluid and includes an azide moiety linked to the surface of a pigment particle. The azide moiety further includes an acidic or a basic functional group bonded to it. An electronic display utilizing the pigment-based ink and a method of formulating the pigment-based ink are also disclosed.
Claims20
Pigment based inks including:
- a non-polar carrier fluid;
- and
- a nitrogen-linked surface functionalized pigment particle, wherein the nitrogen-linked surface pigment particle is suspended in the non-polar carrier fluid and includes an azide moiety linked to the surface of a pigment particle, the azide moiety including an acidic or a basic functional group bonded thereto.
In combination, an electronic display and an electronic ink, wherein the electronic display includes:
- a first electrode;
- a second electrode;
- and
- a display cell having a recess defined by a dielectric material, the first electrode, and the second electrode, the display cell containing the electronic ink;
- and wherein the electronic ink includes:
- a non-polar carrier fluid;
- and
- a nitrogen-linked surface functionalized pigment particle, wherein the nitrogen-linked surface pigment particle is suspended in the non-polar carrier fluid and includes an azide moiety linked to the surface of a pigment particle, the azide moiety including an acidic or a basic functional group bonded thereto.
A method for making a nitrogen-linked surface functionalized pigment particle including:
- providing an azide moiety;
- connecting an amine compound including a functional group to the azide moiety to form an azide including the functional group;
- and
- reacting the azide moiety including the functional group with the surface of a pigment particle to form a covalent bond through a nitrogen of the azide moiety.
