Spin-printing of electronic and display components

A process comprising:

• a) forcing a deposit composition comprising between 0.1 and 70 percent by weight of functional phase particles, a dispersing vehicle, and between 0.1 and 8 percent by weight of an ultrahigh molecular weight polymer soluble in that dispersing vehicle through an orifice to form a fiber
• b) optionally elongating that fiber;
• c) depositing that fiber on a substrate;
• evaporating the dispersing vehicle from the deposited fiber resulting in the functional phase particles affixed to the substrate in the desired image;
• and
• d) and optionally heating the substrate and deposited fiber to a temperature sufficient to effect removal of the organic components.

A process comprising:

• a) depositing from a dispensing orifice a reservoir of a deposit composition comprising between 0.1 and 70 percent by weight of functional phase particles, a dispersing vehicle, and between 0.1 and 8 percent by weight of an ultrahigh molecular weight polymer soluble in that dispersing vehicle on the surface of a substrate;
• b) contacting said reservoir with a finely pointed object wet by the composition;
• c) drawing a fiber from said reservoir by removing the finely pointed object from the reservoir and away from the surface of said substrate;
• d) translating the finely pointed object to an other point above the substrate such that said fiber extends between said reservoir and said other point;
• e) depositing that fiber between said reservoir and another point on the substrate by contacting the finely pointed object to the substrate at that point;
• f) evaporating the dispersing vehicle from the deposited fiber resulting in the functional phase particles affixed to the substrate in the desired image;
• and
• g) optionally heating the substrate and deposited fiber to a temperature sufficient to effect removal of the organic components.

A process comprising

• a) forcing a deposit composition comprising between 0.1 and 70 percent by weight of functional phase particles, and a viscoelastic polymer solution through an orifice to form a fiber;
• b) optionally elongating that fiber;
• c) depositing that fiber on a substrate;
• and
• d) evaporating the volatile components from the deposited fiber resulting in the functional phase particles affixed to the substrate in the desired image, and optionally heating the substrate and deposited fiber to a temperature sufficient to effect removal of the organic components.

A process comprising:

• a) depositing from a dispensing orifice a reservoir of a deposit composition comprising between 0.1 and 70 percent by weight of functional phase particles and a viscoelastic polymer solution onto the surface of a substrate;
• b) contacting said reservoir with a finely pointed object wet by the composition;
• c) drawing a fiber from said reservoir by removing the finely pointed object from the reservoir and away from the surface of said substrate;
• d) translating the finely pointed object to an other point above the substrate such that said fiber extends between said reservoir and said other point;
• e) depositing that fiber between said reservoir and another point on the substrate by contacting the finely pointed object to the substrate at that point;
• f) evaporating the volatile components from the deposited fiber resulting in the functional phase particles being affixed to the substrate in the desired image;
• and
• g) optionally heating the substrate and deposited fiber to a temperature sufficient to effect removal of the organic components.

An ink set that comprises at least two compositions comprising:

• a) between 0.1 and 70 percent by weight of functional phase particles,
• b) a dispersing vehicle,
• c) between 0.1 and 8 percent by weight of an ultrahigh molecular weight polymer soluble in that dispersing vehicle, and
• d) optionally other adjuvants
• e) the second composition comprising:
• f) between 0 and 70 percent by weight of functional phase particles different than those of (b), a dispersing vehicle, and
• g) between 0.1 and 8 percent by weight of an ultrahigh molecular weight polymer soluble in that dispersing vehicle, and
• h) optionally other adjuvants
