Enhancement of Polymer Powder Wettability by Using Surface Dielectric Barrier Discharge

Plasma treatment of polymer powders – from laboratory research to industrial application

“…In the electronics industry, plasma‐treated polymer powders may find application as binder additives for electrode materials in batteries due to higher dispersibility in solvent, or as toners in electro photographic systems thanks to optimized triboelectric charging …”

“…(E) Low‐pressure plasma system V80‐G from PINK Thermosysteme GmbH with a rotary drum made of aluminum for treating small parts . (F) PlasmaFlecto 30 from Plasma technology GmbH with rotary drum for bulk material treatment. (G) PS0500 Tumbler system from Plasma Technology Systems loaded with PE filters .…”

“…Plasma Technology GmbH supplies plasma systems for the laboratory and small series production for cleaning or surface modification of small components. The laboratory system PlasmaFlecto 30 is available with an aluminum rotary drum for bulk material treatment (Figure F). The usable chamber dimensions are 27.5 × 25 × 38 cm (W × H × D) and the system integrates a 600 W power source with an excitation frequency in the kHz range.…”

“…Figure illustrates various atmospheric pressure plasma reactor setups designed to treat polymer powders. These include FBRs, CFBRs, batch reactors, barrel reactors, and downer reactors . Table provides the major experimental characteristics (e.g., power, polymer type, gas, treatment time) of the described setups including main experimental results.…”
