Applications

Flat glass surface cleaning and activation

The video demonstrates the cleaning and activation of ordinary flat (soda-lime) glass by one DCSBD plasma unit at power of 300 W.

The improvement of surface properties is visible after applying of water dispersion onto whole glass surface. The area treated by plasma is immediately covered by a thin water layer whereas the untreated area remained hydrophobic. This effect lasts for one week.

The research results showed that the glass treated by DCSBD plasma becomes hydrophilic due to efficient removal of surface carbon contamination and formation of oxygen-based functional polar groups.

Low-cost high-speed activation of fabrics

The plasma treaters currently used for textile treatment were typically developed as spin-offs of existing technologies, and thus are not optimized for such applications. The DCSBD technique was developed specifically for the in-line textile treatment of fabrics and because of unique character resulting from coplanar arrangement of electrode system, surface plasma of high power density is generated within entire volume of the fabric enables treatment speeds up to 1000 m/min. It is superior to others also in treatment cost efficiency.

Polymer films surface treatment

Polymer films such as PET and PEN are favourable candidates for materials in low-cost printed electronics. Plasma processing of thin non-porous materials requires to keep a specific gap between plasma and the material. For this reason, a curved DCSBD was developed and tested in state-of-the-art prototype treater. The curved DCSBD can be directly used in any roll-to-roll manufacturing line and provides the same efficiency and plasma densities as flat DCSBD. A clear advantage in comparison with standard industrial „corona“ treaters is in unlimited material thickness (suitable also for thick paperboards) and homogeneous treatment without plasma filamentarization.

DCSBD permits the surface treatment of polymer films on a continuous web handling system similar to a „corona“ treating system, but with much higher micro-uniformity, reduced aging, and without unwanted back side treatment. Moreover, it is capable to treat polymer films with printed conductive structures for flexible electronics applications.

Low-temperature high-speed plasma sintering of -nano and mesoporous coatings

Metallic fibres and pre-fabricated coatings containing nanoparticles are usually deposited together with a base polymer or organic binder that are typically sintered/cured by high-temperature processes. This is, however, inappropriate for applications where flexible materials are used as a substrates, e.g. in flexible electronics.

Diffuse coplanar surface barrier discharge treatment for 30 s (up to several minutes) at low-temperature (70 °C) leading to calcination and mineralization of base polymers and organic binders in -nano and meso-porous coatings.

Fast processing by ambient plasma using roll-to-roll could constitute a major step forward in the large-scale manufacture of flexible electronics, among many other application.

Atmospheric plasma treatment of polymer tubing and containers

An atmospheric pressure ambient air plasma technique has been developed for technically simple treatment of inner and/or outer surfaces of plastic tubes and other hollow dielectric bodies. It is based on a specific type of surface dielectric barrier discharge generating visually diffuse plasma layers along the treated dielectric surfaces using water-solution electrodes. The results show that the technique is viable and technically simple alternative to other plasma surface treatments of dielectric hollow bodies. It is flexible, employs simple high-voltage power supplies operated at low frequencies and can be easily modified for economical large-scale applications, as indicated by low energy consumption 0.06 kWh per 1 m2 of the treated tube surface without the use of any expensive specialty gases or water solutions.

Low-temperature treatment of plant seeds

Short plasma treatment of plant seeds is a perspective way for the stimulation and protection of plant seeds. Approximately 1 min of plasma treatment led to complete growth-inhibition of seed-born pathogens. The research and device prototype was done in cooperation with Czech Company SEMO and supported by TACR ALFA project.
