Plasma treatment is a surface modification technique that uses ionized gas, or plasma, to alter the properties of materials. This process can enhance adhesion, wettability, and surface energy, making it useful for various applications, such as improving the bonding of coatings or adhesives on surfaces like plastics and metals. During plasma treatment, materials are exposed to a plasma field, which can be generated using different gases, such as oxygen or argon. The energy from the plasma activates the surface, allowing for better interaction with other substances. This method is widely used in industries like electronics, automotive, and medical devices.
