Steric contributions include interactions between the djsperbyk of the metal nanoparticles and functional groups of polymers or long chain organic molecules, thereby making direct contact between the metal particles e.

DISPERBYK (25KGS/PAIL) – Suka Chemicals

Method for arranging particles and method for manufacturing light-emitting device. 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.

The properties and amounts of these additives and modifiers may be different for each conductive metallic ink, for each substrate, for each printing method, and the like. Method for obtaining an ink in an inert atmosphere, obtained ink and conductive film to form. The following examples are provided to more fully illustrate some of the embodiments of the present invention. It is composed of a solution of a copolymer with acidic groups. The information presented here was acquired by UL from the producer of the product or material or original information provider.


How it works – 1. When the head group is a polymer, the polymer may provide multiple anchoring sites and thus multiple site coverage of the nanoparticle Conductive polymers including, but not limited to, conductive polythiophenes, conductive polyanilines, metallophthalocyanines, and metalloporphyrins may be used to prepare aqueous metallic inks.

Byk invests approximately 7. Epitaxial growth of aligned algainn nanowires by metal-organic chemical vapor deposition. In certain implementations, the polymeric dispersant comprises about 0. Coverage of less than a monolayer leaves open sites on the nanoparticle that may cause agglomeration. Oxidation of copper nanoparticles during printing and curing, however, has been difficult to avoid.

Method of manufacturing nanowire, method of manufacturing a semiconductor apparatus including nanowire and semiconductor apparatus formed from the same. Describes the effects when workers come into contact with the chemical and how to proceed in case of an accident.

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. In addition to the thermodynamic advantage that is gained by having multiple attachment points between the nanoparticle and the head group of a conductive polymer, there is also an advantage in the conducting polymer having a tail group to it.

In some embodiments, a dispersion of metal nanoparticles is formed by adding the nanoparticles to a dispersion of a conductive polymer. When agglomerates are present in a nanopowder, de-agglomeration facilitates formation of a stable dispersion.



In stepa stable conductive ink dispersion including metal nanoparticles, a polymeric dispersant, and a solvent is prepared. Lasers, including continuous and pulsed lasers e. The inventors have discovered that these nanoparticles may be used to prepare well-dispersed inks. Copper particulate dispersion, conductive film forming method and circuit board. Strong interaction between the polymers or the long chain molecules and the solvent or water disprrbyk inhibit the polymers from coming too closely into contact with one another.

A conductive ink comprising: Metal nanoparticles may be added to the conductive polymer dispersion to form a metal nanoparticle dispersion. In some cases, the metallic surface may be heterogeneous, having both negatively and positively charged sites. The carrier may be, for example, water, an organic solvent, or any combination thereof. The maintenance of a disperbbyk may be assisted by mechanically breaking up the agglomerates with a ball mill or other device, sonication e.

Therefore, charged conductive polymers having oppositely charged polyacid functionalities for charge compensation may be used to advantageously disperse metal nanoparticles in aqueous inks.

During photosintering, metallic nanoparticles are adhered together during photonic curing to form metallic films.
