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.

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.
