Company Byk has an established history of innovation such as being the first additive manufacturer to begin using Controlled Polymerization Technology CPTlaunching the first rheology-modified wax emulsion, and being one of the first companies to use nanotechnology for improving Coatings properties.
Method for producing metal particles, ink composition and paste composition produced by the same. Steric stabilization of metal nanoparticles may be achieved with a non-ionic dispersant or polymer.
This multi-site attachment of a polymer to a nanoparticle leads to a thermodynamic advantage over a dispersant that only attaches via a single site.
Controlling ink migration during the formation of printable electronic features. Colloid solution of metal nanoparticles, metal-polymer nanocomposites and methods for preparation thereof. For passivated metallic nanoparticles, the metal oxide layer may be photoreduced to elemental metal, resulting in high-purity metallic conductors. 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 dosperbyk combination thereof.
Ddisperbyk shearing such a system beyond a yield stress, it becomes liquid and thus flows easily. Ag plating excellent in re – Dofure – beam materials for Fe-Ni alloy and manufacturing method thereof.
In stepdixperbyk ink is applied to a substrate. It is composed of a solution of a copolymer with acidic groups. Fine metal particles and fine metal oxide particles in dry powder form, and use thereof. A stable dispersion, or copper ink, was obtained after agitation. The printed and dried inks may be cured.
Supply of DISPERBYK-110
If a second monolayer of dispersant is present on the nanoparticle, the second layer may be oriented in the opposite direction from the first layer, thereby reducing the compatibility of the nanoparticle with the solvent. The addition of 0. 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 dosperbyk within.
Other printing methods, including spin-casting, spraying, screen disperbgk, flexo printing, gravure printing, roll-to-roll coating, and the like, may also be used for depositing conductive metallic inks. In some cases, nanoparticles in a metallic nanopowder may be agglomerated through a salt bridge, including a soluble salt precipitated in the formation of the nanopowder. Process for preparation of silver nanoparticles, and the compositions of silver ink containing the same.
Electrical circuit component formed of a conductive liquid printed directly onto a substrate. Such compounds have high boiling points or decomposition temperatures, and are difficult to remove during a curing process. Dispersion comprising metallic, metal oxide or metal precursor nanoparticles, a polymeric dispersant and a sintering additive.

Electronic components, electronic component manufacturing method and circuit board. Find out how we can help here. Silver nanoparticle ink composition for highly conductive features with enhanced mechanical properties.
Ink composition for preparing front electrode of solar cell and solar cell comprising the same. Non-metallic portions of the substrate may not be directly heated by the absorbed light. In contrast, the photonic curing process occurs in a fraction of a second, and no significant oxidation occurs before the copper cools back to ambient temperature. At low pH, the hydroxide surface may react with protons to produce a positively charged surface.
Method of laser bonding for gold, gold coated and gold alloy coated electrical members. It reduces haze in inorganic pigmented coatings when application occurs by electrostatic spraying. Instructions on what protective equipments should be used to handle the materials. Substrates with a high surface energy, including flexible substrates such as polyimide, require different additives and modifiers than substrates with a low surface energy, such as glass, silicon, or low surface energy polymeric substrates.
For some conductive inks, such as copper inks, curing may be achieved by photosintering. For conductive films formed by photosintering copper inks with non-ionic dispersants, a resistivity as low as about 3. You may choose a language below to continue to this industry or close this dialog above. The information presented here was acquired by UL from the producer of the product or material or original information provider.
A weight ratio of IPA: Surface preparation to eliminate whisker growth caused by plating process interruptions.
Metallic nanoparticles may have an oxide layer on their surface. Another advantage of a high exclusion volume is that it allows for a low concentration of dispersant to be used, and therefore, only a small quantity of dispersant to be removed during the curing process. This material, compatible with both organic-solvent-based and water-based inks, may be used in an amount ranging from about 0. Thus anionic and cationic dispersants may be adsorbed onto the surface of metal nanoparticles under conditions that depend on the pH of the solution or dispersion.
In some implementations, the polymeric dispersant may be ionic, non-ionic, or any combination of ionic and non-ionic polymeric dispersants. For example, ink formulations with low boiling-point solvents and dispersants leave little organic residue after film formation e.

xisperbyk In each case, the multifunctional structure allows for low concentrations to be used to achieve stable nanoparticle dispersions.
Conductive polymers including, but not limited to, conductive polythiophenes, conductive polyanilines, metallophthalocyanines, and metalloporphyrins may be used to prepare aqueous metallic inks.
In a dispersion, the dispersant may act as a molecular bridge between the nanoparticle and the vehicle, thereby keeping the nanoparticles separated by one or more molecular layers. A method for the production of conductive and transparent nano-coatings and nano-inks and nano-powder coatings and inks produced thereby.
These salt bridges may be dissolved by a dispersant to break up the agglomerates.
