“…12 An inverted configuration, where the needle is the grounded electrode and the plate electrode is biased, was used to increase the removal efficiency of aerosol particles from the gas using a grounded atomizing water discharge electrode. 13 The use of inverted corona setup during polymer treatment is interesting, since the needle can be safely filled with grounded liquids, thus being a source of ions derived from the liquid vapor. This type of experiment is difficult to control when using a biased needle as in the conventional geometry, because the reduction of surface tension of the biased liquid exiting the needle forms elongated jets that break into droplets.…”

Top and bottom surfaces of polyethylene (PE) films exposed to corona discharge display large and opposite electrostatic potentials, forming an electric bilayer in agreement with recent and unexpected findings from Zhiqiang et al. Water wetting, chemical composition and roughness of the two surfaces are different. Surprisingly, the bottom surface, opposite to the corona electrode is charged but it is not oxidized, neither is it wetted with water. Moreover, its morphology is unaltered by charging, while the hydrophilic top surface is much rougher with protruding islands that are the result of oxidation followed by phase separation and polymer−polymer dewetting. Common liquids extract the oxidized, hydrophilic material formed at the upper surface, a result that explains the well-known sensitivity of adhesive joints made using corona-treated thermoplastics to liquids, especially water. These results show that poling the surface closer to the corona electrode triggers another but different charge build-up process at the opposite surface. The outcome is another poled PE surface showing high potential but with unchanged chemical composition, morphology and wetting behavior as the pristine surface, thus opening new possibilities for surface engineering.

“…Many experts and scholars to study in the field of electric dust collector, wet film electric dust collector is a hot topic of current research. Membrane materials has been applied to the ESP, and made very good results [1]. In the paper, V-I (Voltage-Current) characteristic of carbon fiber is compared with V-I characteristic of metal plate.…”

This paper focuses on V-I characteristic of the carbon fiber membrane collecting under the four corona electrode which are square oblique second tooth white prick line, prick plate 20mm tooth long, prick plate 30mm tooth long and 40mm. Respectively research voltage characteristic of dry film collecting and wet film collecting, the comparison of dry film collecting and metal plate in the same condition. The result is that carbon fiber membrane can completely replace metal plate collecting pole the more storage of collecting membrane, the higher corona current, it is benefit for collecting. Wet film relative to the dry film, provides a higher voltage spark discharge, in order to maintain higher electric field strength, which is very beneficial for collecting.
