Customized Nanocoating on Palladium Substrate

Palladium is a silver-white metal with a low melting point and low density that is uncommon and beautiful. Palladium is most commonly employed in catalytic converters in modern technology, but it can also be found in jewelry, dental materials, watch accessories, blood sugar test strips, surgical equipment, and electrical contacts. Palladium metal with functional surfaces provides numerous performance benefits in a number of applications.

Alfa Chemistry offers palladium metal customers bespoke functionalized surface coating services. With our wide choice of easy-to-apply specialty coating treatments, you can improve the performance of practically any product utilizing palladium. Work with us to make your palladium surfaces functional!

Extensive Surface Modification Technology Options

Alfa Chemistry provides a number of surface coating technologies that may be used to functionalize gold surfaces for a variety of performance advantages. For palladium, we have a variety of surface modification technology possibilities, including but not limited to:

• Surface Waterproofing Coating Technology - We can make palladium substrates very water and oil repellent by functionalizing the surface, making them highly repellent to practically any liquid.
• Hydrophilic Coating Technology - Palladium substrates can be functionalized to make them very hydrophilic.
• Adhesion Promotion Coating Technology - We can functionalize palladium substrates to improve the adhesive qualities of the surface using adhesion promotion coating technology.
• Particle Modification Coating Technology - To improve particle behavior, minimize aggregation, and maximize cross-linking, Alfa Chemistry can functionalize palladium powder and gold particles.
• Lubricant Coating Technology - Palladium substrates can be functionalized to reduce surface friction.

We can create nanoscale, optically transparent, and long-lasting coatings.

Alfa Chemistry Coating Solution Cases

Case 1: Improved catalytic performance with polydimethylsiloxane coating

Alfa Chemistry covers Pd/UiO-66, which is a metal-organic framework (MOF) and stabilized palladium nanoparticles, with a thin coating of hydrophobic substance polydimethylsiloxane (PDMS) through chemical vapor deposition (CVD) to make its surface hydrophobic (NPs). The hydrophobic coating aids in the enrichment of hydrophobic substrates and hence interaction with Pd sites, as well as protecting and inhibiting Pd NP aggregation. PDMS-coated Pd/UiO-66 showed dramatically higher catalytic efficiency and recyclability. A variety of Pd-based catalysts can now discriminate between hydrophilic and hydrophobic substrates thanks to PDMS coatings.
