Customized Nanocoating on Cadmium Sulfide Substrate

INQUIRY

Cadmium sulfide is a chemical compound that is made up of inorganic elements. It is the major source of cadmium for all commercial uses since it is a simple to extract and purify chemical. Cadmium sulfide and cadmium selenide can combine to generate a solid solution, which is used to make a photoresistor that detects visible and near-infrared light.

Alfa Chemistry provides one-of-a-kind surface modification services for cadmium sulfide substrates with functional surfaces that improve performance in a variety of applications. You may improve the surface features of nearly any cadmium sulfide-related product with our easy-to-apply surface treatment technology. Please contact us if you'd like to simply change the surface properties of your items.

Extensive Surface Modification Technology Options

Alfa Chemistry provides customers with a number of semiconductor surface coating methods that can be used to functionalize the surface of cadmium sulfide materials and impart a variety of surface features. The following are some of our surface alteration technologies, but they are not exhaustive. Please contact us for more information on our technologies.

  • Surface Waterproof Coating Technology - On the surface of cadmium sulfide materials, we can add hydrophobic and oleophobic qualities, making them highly water and oil resistant and efficient against all liquid penetration.
  • Particle-modified coating technology - By functionalizing cadmium sulfide particles, we can improve particle behavior, reduce aggregation and improve cross-linking.
  • Adhesion Promotion Coating Technology - By functionalizing the surface of cadmium sulfide materials, we can improve their surface adhesion.
  • Lubricant coating technology - We are able to lubricate the surface of functionalized cadmium sulfide materials to improve their surface friction properties.

Alfa Chemistry Coating Solution Cases

Case 1: Surface coating of cadmium sulfide quantum dots

Quantum dots (QDs) are commonly used in a variety of applications, including electronics and medical. Alfa Chemistry can modify the surface of cadmium sulfide quantum dots (CdS-QDs) to support plant research.

Examples include studying the bioaccumulation and biological response of CdS-QDs compared to Cd2+ ions and bulk CdS through soybean seedlings. To learn more about how surface coatings affect quantum dot stability, uptake, translocation, subcellular localization, and cellular responses, we modified bare CdS-QDs with a variety of polar and surface-charged ligands. To prepare QD-TOPO, QD-PVP, QD-MAA, and QD-GLY, four common ligands were used: trioctylphosphine oxide, polyvinylpyrrolidone, thioglycolic acid, and glycine. acetic acid and glycine.
