Technology

DCSBD technology

ROPLASS is currently pursuing its DCSBD technology that promises to solve some of the major challenges in different industrial branches. Our DCSBD technology is capable to create a thin layer of macroscopically uniform high-density plasma. Already successfully conducted laboratory tests have revealed following unique properties of our DCSBD plasma technology that clearly differentiate it from other plasma technologies:

  • Homogeneity of DCSBD plasma increases with the discharge power density
  • The power density of thin diffuse DCSBD plasma layer achieves the order of 100 W/cm3
  • The macroscopically uniform plasma with the high power density can be generated in any, even in strongly electron-attaching, reactive gas mixture
  • DCSBD plasma is mechanically robust and safe
  • DCSBD plasma is capable to meet the on-line production requirements in textile and paper industries, particularly in nonwovens industry
  • No noble gas admixtures (helium, argon) necessity to create homogeneous plasma with DCSBD technology
  • Excellent durability of DCSBD plasma surface activation

DCSBD – based surface treatment could be of use for you as it is highly innovative, effective, low cost and environmentally friendly technology.

DCSBD technology developed by ROPLASS is focused on both surface treatment and deposition of functional coatings. Our atmospheric plasma technology is able to treat the materials such as polymers, fabrics, wood, paper and others in a safe, environmentally friendly and cost-effective way. What is the DCSBD’s potential to do with treated substrates?

Applications

Flat glass surface cleaning and activation

DCSBD plasma treatment in ambient air leads to significant improvement in glass wettability. This is because adsorbed carbon contaminants efficient removal and formation of polar hydrophilic groups. The higher wettability is often related with better adhesion of coating on glass.

Roll-to-roll processing of polymer foils and paper

Curved DCSBD plasma unit designed for roll-to-roll processing of polymer foils provides efficient inline treatment of thermoplastics (PMMA, PEN, PET), other polymers and paper, including paperboards, where higher thickness is problematic for corona treaters. Since plasma has no damage effect on treated materials, the method can be adopted for application of flexible and printed electronics.

 

Fast and low-temperature (70 °C) sintering of functional coatings

Mesoporous TiO2 photoanode

Functional films and coatings, often used in printed electronics, are usually deposited together with a base polymer or/and organic binder. Prior to application, the polymeric or organic binder must be removed from the coating and this is typically achieved by high-temperature (~400 °C sintering). However, the high-temperature sintering precludes the use of a functional film on thermally sensitive polymeric foils that are essential for printed electronics.
High power-density and low-temperature (70 °C) DCSBD plasma treatment for 10s of seconds (up to several minutes) has similar effect as high-temperature sintering. Recently reported research papers showed that DCSBD plasma treatment enables to manufacture functional mesoporous photoanode on flexible PET. The DCSBD plasma technology constitutes a major step forward in the large-scale manufacture of flexible printed electronics by roll-to-roll fashion.

Fast and low-temperature (70 °C) reduction of nanostructured oxide coatings

Advanced surfaces manufacturing and environmental protection policy demand implementation of new technologies in the coming era. The DCSBD enables to generate diffuse and stable plasma in argon, hydrogen and methane and other reducing gases; at atmospheric pressure, large-area and roll-to-roll fashion. Research results showed that very short hydrogen plasma treatment of graphene oxide leads to fast reduction to graphene with enhanced functional attributes. As well as graphene manufacturing, hydrogen plasma treatment enables manufacture of copper electrodes and synthesis of various nanoparticles. Since the entire plasma process is at low-temperature and requires short times, it is suitable for roll-to-roll processing and can be utilized also for printed electronics.
