Atmospheric plasma

What is Plasma ?

The addition of energy into matter modifies electromagnetic forces, binding atoms together. The state of matter evolves from solid to liquid, then from liquid to gas. Adding even more energy dissociates molecular bonds and may lead to ionization. Gas molecules are split into charged particles, ions and free electrons.

Plasma can be considered as "the fourth state of matter".    

 

Generating a plasma under atmospheric pressure

 Atmospheric plasmas are produced by electrical discharge through a gas. Firstly, gas is continuously injected into the plasma generator, then ionized and finally directed towards the surface to be treated.
By controlling the electrical discharge a low temperature plasma is generated. At high processing speeds, there is no risk to increase the surface temperature of the treated materials. Therefore, even heat-sensitive materials, like some polymers, can be treated without damage.    

Effects on surfaces

Plasma consists of a continuous supply of a highly reactive chemical species used for treating surfaces. Plasma cleans or activates surfaces.
Activation is the modification of the composition of a surface, resulting in a change of its surface energy. Surface wettability can be drastically increased by grafting polar functions. As a consequence, it promotes a stronger adhesion for paints, inks, glues or varnishes. Plasma activation is a simple process that allows a wide range of surface improvements.    

Thin film coating

Atmospheric pressure plasma is also a very cost efficient process for thin film deposition. Chemical precursor reacts with the plasma and then creates thin films on the substrate.    

 

IONICS is the official distributor for AcXys Technologies in the BENELUX. AcXys Technologies is one of the leading companies providing efficient, clean and economic atmospheric pressure plasma solutions.    

 

   

We also have an atmospheric plasma torch based on the Microwave technology, called IONJET. Unlike classical plasma torches, this new technology generates a plasma at the outlet of the torch and maximizes the energetic species available to interact with the substrates surface.
