Study the Material safety data sheets for the hazards of the chemical, learn the instructions on handling, storage and the emergency measures in case of accident. In dipserbyk cases, nanoparticles in a metallic nanopowder may be agglomerated through a salt bridge, including a soluble salt precipitated in the formation of the nanopowder. Sinterable disprrbyk material using copper nanoparticles, process for producing same, and method of bonding electronic component.

Some or all of these steps are described in detail in the examples below. Selection of additives and modifiers for a conductive ink formulation may depend on physico-chemical properties of the vehicle system, the substrate, or any combination thereof.

In some embodiments, a dispersion of metal nanoparticles is formed by adding the nanoparticles to a dispersion of a conductive polymer.

A larger excluded volume separates metal djsperbyk more effectively than a smaller excluded volume, and provides a high level of coverage of the nanoparticle with a low concentration of dispersant.

Method for producing metal particles, ink composition and paste composition produced by the same. These additives may be, for example, polymeric materials having different chain lengths, terminal end groups, side chains, and co-polymeric chains that introduce the desired properties into the conductive inks. Additives and modifiers used in conductive metallic inks may act as rheology modifiers, wetting agents, adhesion promoters, binders, defoaming agents, leveling agents, ionic strength modifiers, and the like.

Ink coating appearance or quality, as determined by coating uniformity and the absence of holes, may be improved by modifiers or additives that reduce ink surface tension, enhance metal wettability, promote ink defoaming, and the like.

For conductive films formed by photosintering copper inks with non-ionic dispersants, a resistivity as low as about 3. The ink of claim 1wherein the polymeric dispersant is non-ionic. The method of making the metal mesh conductive film, the metal mesh conductive film of the touch panel.

Preserving solderability and inhibiting whisker growth in tin surfaces of electronic components. Electrical circuit component formed of a conductive liquid printed directly onto a substrate. Aqueous formulation containing silver, and its use for production of electrically conductive or reflective coatings.

Ink for ink jet printing and method for preparing metal nanoparticles used therein. My aim is to give back to those of you that have been affected by chemical incidents and to help bring positive change to your world.

As an additive to conductive inks e. Method for obtaining an ink in an inert atmosphere, obtained ink and conductive film to form. The solubility of the tail group of the dispersant in the vehicle is also a factor in the selection of a dispersant for a given ink formulation. Conductive polymers including, but not limited to, conductive polythiophenes, conductive polyanilines, metallophthalocyanines, and metalloporphyrins may be used to prepare aqueous metallic inks. Stabilizing agents are weakly gel forming polymers where upon quiescent storage or very low shear they become semi-solid, thus inhibiting aggregation and sedimentation of particles suspended within.


Any copper oxides that are present on the surface of the copper nanoparticles are at least partially photoreduced, as shown in the X-ray diffraction patterns in FIG. Conductive paste for filling via-hole, double-sided and multilayer printed circuit boards using the same, and method for producing the same. Conducting polymers with multiple binding sites may partially surround a metal nanoparticle, thereby keeping it from aggregating or agglomerating. A dosage of 0. The addition of 0.

The information presented here was acquired by UL from the producer of the product or material or original information provider.

The carrier may be, for example, water, an organic solvent, or any combination thereof. The ink of claim 16wherein the dispersant is selected from the group consisting of phosphoric acid modified phosphate polyester copolymers, sulfonated styrene maleic anhydride esters, and any combination thereof. Dispersion adjuvant for metal nanoparticles and metal nanoink comprising the same.

TEGO Datasheet; http: Dusperbyk the curing process, the copper nanoparticles dispegbyk fused during the very short curing time, while little or no damage occurs to the substrate, and copper oxides that are present on the surface of the copper nanoparticles are at least partially photoreduced. Metal article coated with tin or tin alloy under tensile stress to inhibit whisker growth.


Photovoltaic thin-film cell produced from metallic blend using high-temperature printing.

Quaternized alkyl imidazoline ionic liquids used for enhanced food soil removal. Recently, metal nanoparticles having consistent size and shape have been developed.

Dispersion comprising metallic, metal oxide or metal precursor nanoparticles, a polymeric dispersant and a thermally cleavable agent. The head group of a dispersant may be selected such that the functionality of the group is compatible with the metal nanoparticle in an ink formulation. The HCS conducting polymer suspension with copper nanoparticles Example 5A yielded a film with a resistivity of 4.

Intumescent paint coatings for inhibiting tin whisker growth and methods of making and using the same. In some implementations, the polymeric dispersant may be ionic, non-ionic, or any combination of ionic and non-ionic polymeric dispersants. Solvents including mixtures of i 2-butoxyethyl acetate and propylene glycol monomethyl ether acetate, ii 2-ethoxyethyl acetate and propylene glycol monomethyl ether acetate, iii 2-ethoxyethyl acetate and amyl acetate, and iv ethylene glycol diacetate and propylene glycol monomethyl ether acetate are effective vehicle systems for ink formulations with both ionic and non-ionic dispersants.

This optical curing step was carried out in air at room temperature. The solution was agitated for at least 20 minutes to break up any agglomerated copper nanoparticles and to mix the dispersion. After de-agglomeration, dispersion stability may be maintained by achieving a balance between attractive and repulsive forces in an ink formulation. Variation in substrate porosity, and consequently, differences in absorption of the conductive ink, may also influence selection of additives and modifiers for a conductive ink formulation.

Other printing methods, including spin-casting, spraying, screen printing, flexo printing, gravure printing, roll-to-roll coating, and the like, may also be used for depositing conductive metallic inks. Printed conductive films have the potential to lower manufacturing costs for microelectronics and large area electronics.

Lower concentrations of the dispersant are favorable because less organic material remains after the curing process. These additives provide the ink with wetting and surface tension properties to allow compatibility with the substrate surface and printing equipment, such as ink-jet nozzles, and help maintain a uniform dispersion needed for homogeneous print quality.
