Embodiment 1

[0108] Tables 1 and 2 below illustrate the preparation of the conductive composite material according to the present invention. The ingredients of Table 1 were mixed as described to form a matrix, and then combined with the ingredients of Table 2 so that the composition of Table 1 accounted for about 20% by weight of the obtained composite material. The resulting composite material is cured by ultraviolet radiation.

[0113] The material is applied to a thickness of approximately 20 microns in an area of ​​1 mm wide and 75 mm long. The resistance measurement is performed and converted into resistivity (1 / conductivity) by the following equation: resistivity=(resistance×width×thickness) / length. After UV curing, the obtained material immediately showed 1395×10 at 23℃ -8 Resistivity (Ohm-m), 737×10 after four days of curing -8 After that, the resisti...

Embodiment 2

[0115] The following table exemplifies the preparation of the conductive composite material according to the present invention. This embodiment exemplifies a composition generally formed by the following steps: mixing monomers (optionally in the presence of a wetting agent), adding a conductive material to it, and then adding a photoinitiator and optional organofunctional silane. At concentrations within ±10% of the stated value, similar results are expected.

Abstract

The present invention is directed to a conductive article and method of making the same that includes a substrate (10); a conductive composite (14) including a conductive material in a matrix that includes one or more film forming resins having at least one functional group capable of polymerization; one or more adhesion promoters; and one or more compounds, which are reactive with the film forming resin and which also contain at least one acidic moiety.

Description

[0001] Priority claim [0002] This application requires the rights and interests of the submission date of provisional application number 60 / 870,639 (submitted on December 19, 2006), all of which are incorporated herein as reference. Technical field [0003] The present invention relates to a conductive composite article, especially a transparent substrate, on which a conductive composite layer is selectively applied on the surface of the substrate, such as for heating windows. Background technique [0004] In the field of automotive glass applications, a method of manufacturing a window defogger is to apply a paint with conductive particles on a glass substrate, and then fire the material to ensure electrical communication between the conductive particles. See, for example, U.S. Patents 7,138,347 and 5,795,501 (both of which are incorporated by reference). This potentially limits the use of some materials. For example, many transparent plastics cannot withstand the extreme condi...
