Abstract
Resistive inks and method of making resistive inks that utilize a phthalonitrile resin as a curable component in the inks are disclosed. In one example, a resistive ink is provided. The resistive ink comprises a solvent, a thermally-curable phthalonitrile-based resin dissolved in the solvent, and one or more conductive fillers. In some examples, the phthalonitrile resin can comprise a B-staged material.
Claims20
A resistive ink, comprising:
- a solvent;
- a curable phthalonitrile resin dissolved in the solvent;
- and
- one or more conductive fillers.
A method of making a resistive ink, the method comprising:
- mixing a phthalonitrile resin, a conductive filler, and a solvent to dissolve the phthalonitrile resin in the solvent and to form the resistive ink.
A method of making a high temperature resistive film and/or cured adhesive, the method comprising:
- applying a resistive ink comprising a phthalonitrile resin, a solvent, and one or more conductive fillers on a substrate;
- evaporating the solvent from the resistive ink;
- and
- curing the phthalonitrile resin on the substrate by activating a catalyst contained in the resistive ink.
