Plasma processing is a technology that uses ionized gas, or plasma, to modify the surface of materials. This process can enhance properties like adhesion, wettability, and chemical resistance. It is commonly used in industries such as electronics, textiles, and biomedical applications to improve product performance. During plasma processing, materials are exposed to plasma created by applying energy to a gas, which can be inert or reactive. The interaction between the plasma and the material's surface leads to changes at the molecular level, allowing for precise control over surface characteristics without altering the bulk properties of the material.
