Vetyperoksidigasplasma

Vetyperoksidigasplasma, often abbreviated as H2O2 plasma, refers to a non-equilibrium plasma generated from hydrogen peroxide (H2O2) vapor. This type of plasma is characterized by a high concentration of reactive species, including oxygen atoms, hydroxyl radicals (OH), and ozone (O3), in addition to excited hydrogen and oxygen molecules. The generation process typically involves dissociating H2O2 molecules, either through electrical discharges such as dielectric barrier discharges (DBD) or microwave plasmas, or by using thermal energy.

The unique chemical composition of vetyperoksidigasplasma makes it highly reactive and effective for various applications. It is known for its potent oxidizing and sterilizing capabilities. These properties stem from the ability of the reactive species to break down organic molecules, inactivate microorganisms like bacteria and viruses, and modify surface properties of materials.

Key applications of vetyperoksidigasplasma include surface sterilization and disinfection in healthcare settings, food packaging, and electronics manufacturing. It is also utilized for surface modification, such as cleaning, etching, and the deposition of thin films, particularly in the semiconductor industry. The ability to operate at low temperatures is a significant advantage, allowing for the treatment of heat-sensitive materials without causing damage. Research continues to explore its potential in areas like environmental remediation and biomedical applications.
