Plasma treatment solutions enable the modification of surface characteristics at a microscopic (nanoscale) level, to clean, activate, etch and coat materials. Therefore Plasma treatment is used in a variety of industries; such as medical and life sciences, electronics and filtration… Plasma technology’s advantages make it a versatile and efficient choice for various surface treatment applications.
In atmospheric plasma systems materials can be moved through a treatment zone via a conveyor belt. (Niemira, 2012) The film is processed continuously.
The biggest general benefit of plasma technology for surface treatment solutions is the controlled atmosphere in which the process is executed.
The plasma treatment process is performed at ambient pressure.
Depending on the chemistry, different types of processes are performed.
The Coating Plasma Innovation (CPI) division offers two kinds of treatment: grafting or coating.
- For grafting the substrate is exposed to the highly reactive species of the plasma gas. The interactions between the substrate and those species will modify the surface chemistry. New chemical functions will be grafted on the material surface. The nature of the grafted functionalities can be adjusted by carefully controlling the gas composition.
- For coating, vapors of a specific molecule are added to the plasma gas. Those vapors are activated by the energetic species in the plasma and will react on the surface to create a coating. This process is called AP-PECVD (Atmospheric Pressure Plasma Enhanced Chemical Vapor Deposition). Depending on the nature of the precursor, coating with very specific properties can be deposited.
Atmospheric plasma systems are reliable and have a good operational equipment efficiency.
