Customized Nanocoating on Polysiloxanes Substrate


Polysiloxanes are a type of silicone polymer that is widely used in polymer chemistry. Flexibility, gas permeability, low glass transition temperature, and low surface energy are all features of polysiloxanes. The linear polydimethylsiloxane is the most frequent variety (PDMS). Polysiloxanes have a wide range of medicinal and non-medical applications due to their various characteristics. This polymer is a popular option for a wide range of applications. Prosthetics, artificial organs, facial reconstruction, catheters, artificial skin, contact lenses, and drug delivery systems are examples of medical applications, while high performance elastomers, membranes, electrical insulators, water repellents, defoamers, mold release agents, adhesives, and protective coatings are examples of non-medical applications.

In a wide range of applications, polysiloxanes with functional surfaces can give numerous performance advantages. For polysiloxane materials, Alfa Chemistry offers a variety of functionalized surface coating processes. Using our wide and straightforward surface modification methods, you can improve the surface quality of nearly any polysiloxane-related product.

Extensive Surface Modification Technology Options

Alfa Chemistry provides a variety of polymer surface coating technologies to its customers in order to functionalize the surface of polysiloxanes materials in various categories and improve their varied surface qualities. The following are some of our surface modification technology possibilities, however they are not exhaustive. For more technology please contact us.

  • Surface Waterproof Coating Technology - We can add hydrophobic and oleophobic qualities to the surface of polysiloxanes to make them highly water and oil resistant, effectively making them immune to nearly all liquids.
  • Hydrophilic coating technology - By functionalizing the surfaces of polysiloxanes, we can make them very hydrophilic.
  • Adhesion Promotion Coating Technology - We can increase the surface adherence of polysiloxanes by functionalizing their surface.
  • Particle-modified coating technology - Alfa Chemistry can improve particle behavior, minimize aggregation, and maximize cross-linking by functionalizing the surface of polysiloxanes particles.
  • Lubricant Coating Technology - We can functionalize the surface of polysiloxanes substrates with lubrication to modify their surface friction properties.

These nanoscale coatings can be manufactured and are chemically stable, optically transparent, and highly durable.

Alfa Chemistry Coating Solution Cases

Case 1: Preparation of nickel/copper coatings on polysiloxanes substrates

Electroplating is a low-cost surface modification process that has been investigated on various types of substrates in recent years, using which uniform coatings can be easily obtained and metallic films can be fabricated on polymer surfaces. Metallic catalysts have poor adhesion and wear resistance and tend to peel off in the plating solution.

Alfa Chemistry roughens the surface by preparing an intermediate layer on the surface of polysiloxanes substrates. Increasing the surface roughness improves mechanical anchoring and contact area, which in turn enhances the adhesion of the metal coating.
