Dielectric coating compositions are provided. The dielectric coating compositions generally include an aqueous binder, an inorganic nanoparticle, and a solvent, and can be formulated for specific printing methods, such as inkjet printing. The dielectric coating compositions are curable to provide scratch resistant coatings useful as insulating layers.

Thermal cure dielectric ink

Described herein are adhesive gold inks, and methods for making and depositing these inks to form conductive traces. The adhesive gold inks generally contain a gold complex dissolved in a mixed solvent system including at least a diol and an amine. The mixed solvent system may further include a thioalkyldiol. The gold complex includes a first ligand and a second ligand. The first ligand may be a thioether, a phosphine, or an amine that volatilizes upon heating at a temperature of 200&#xb0; C. or less. The second ligand may be a halide or a carboxylate. The adhesive gold inks are clear and particle-free and may be formulated for deposition by a wide range of printing methods on both flexible and non-flexible substrates.

Particle-free adhesive gold inks

Described herein are methods for forming e-textiles, wherein the methods include printing a particle-free conductive ink on a textile substrate, and curing the textile substrate to produce a conductive pattern thereon. The printing may include inkjet printing and may produce a printed pattern which exhibits an ink bleed of less than 0.5 mm, such as less than 0.2 mm. During printing, the textile substrate may be heated to a temperature of 30&#xb0; C. to 90&#xb0; C. before and during the printing process. The fabric substrate may be cured using heat and/or light to produce a conductive pattern having a sheet resistance of less than 10&#x3a9;/&#x25a1;, or even less than 1&#x3a9;/&#x25a1;.
