Abstract
Described herein are printheads for inkjet printing and, more specifically, printheads modified with a self-assembly monolayer (SAM). Also described are processes for making and using the printheads as well as processes for forming patterns and images on a substrate including jetting inkjet inks or jettable materials using a printhead for inkjet printing that has been modified with a self-assembly monolayer.
Claims18
An inkjet printhead comprising a self-assembly monolayer (SAM) formed on at least a printing surface and an inside of a printing orifice of the inkjet printhead, wherein an advancing water contact angle variation at room temperature between any two locations on the printing surface of the printhead is less than 5 degrees.
A method of forming an image comprising printing an ink on a substrate with an inkjet printer, wherein the inkjet printer comprises a printhead with a self-assembly monolayer (SAM) formed on at least a printing surface and an inside of a printing orifice of the inkjet printhead, wherein an advancing water contact angle variation at room temperature between any two locations on the printing surface of the printhead is less than 5 degrees.
A method of forming an electronic device comprising printing a functional material ink on a substrate using a precision material deposition system, wherein the precision material deposition system comprises a printhead with a self-assembly monolayer (SAM) formed on at least a printing surface and an inside of a printing orifice of the inkjet printhead, wherein an advancing water contact angle variation at room temperature between any two locations on the printing surface of the printhead is less than 5 degrees.
An inkjet printhead comprising a self-assembly monolayer (SAM) formed on at least a printing surface and an inside of a printing orifice of the inkjet printhead, wherein an advancing water contact angle variation at room temperature between any two locations on the printing surface of the printhead is less than about 5 degrees, and wherein the SAM is derived from a precursor X—Y, wherein X is a reactive group selected from the group consisting of —PO3H3, —OPO3H3, —COOH, —SiCl3, —SiCl(CH3)2, —SiCl2CH3, —Si(OCH3)3, —SiCl3, —Si(OC2H5)3, —OH, —CONHOH, —NCO and —C6H4N3, and Y is a hydrocarbon structure or a fluorocarbon structure.
