Assignee:

Shipley Company, L.L.C. - Marlborough MA

International Classification:

H01C001/012

US Classification:

338/307000

Abstract:

Resistive materials having resistivities that are axis dependent are provided. Such resistive materials having a resistivity in a first direction and a very different resistivity in an orthogonal direction. These resistive materials are particularly suitable for use as resistors embedded in printed wiring boards.

Abstract:

The process of the present invention significantly increases the durability of superhydrophobic surfaces, while retaining similar optical properties to those of the original surface. The process uses velocity and heat to take freshly formed nano- and ultrafine particles and can partially embed and chemically bond them to the substrate, creating a strongly bonded nano-to-submicron textured surface. This nanotextured surface can then be modified to have desirable surface properties; for example, it can be hydrophobic, oliophobic, or hydrophilic. The high points of the coating made with this process protect the remainder of the surface from abrasion, thus greatly increasing product life in many uses. In preferred embodiments, the process is used to coat transportation vehicle windshields.
