Simplified Manufacturing of Ink, Water, Oil, and Grime Repelling Coating

Executive Summary

Researchers at Michigan State University have developed a new omniphobic polyurethane coating with the ability to repel many types of liquids (such as ink, water, and oil) and other materials. This technology is Fluorine-free and cost effective to manufacture. The coating not only repels liquids, but is mechanically durable once applied to a surface. At several microns thick, this coating is optically clear, making it an ideal choice for windows, mirrors, or screens. Since liquids bead up and roll off the surface this coating has a ‘self-cleaning’ property, such that rain or a light wash liquid will more easily remove contaminants repelled by the surface.

Description of Technology

While there are products that excel at repelling water, few have the ability to repel multiple forms of liquids; particularly inks. Even fewer are Fluorine-free, a precursor element known to make manufacturing coatings costly. To reduce costs even further, this technology is manufactured using a simple and cost effective one-pot approach. This coating may be used, for example, with glass, coat fibers, metals, wood, fabrics and ceramics with relative ease.

Key Benefits

Mechanically durable – Scratch resistant coating
Simpler Processing– One pot synthesis reduces manufacturing steps
Cheaper – Removal of Fluorine, graft/block copolymers eliminates expensive raw materials
