3 2-; Positive corona produce by the proton (H that is different humidity
2o)
nh
+, and the NO of wet type
+and NO
2 +, due to the reduction of relative humidity, both cations are incited somebody to action more horn of plenty afterwards, and these ions can be used as integral body and are adsorbed in polymer surfaces or superficial layer.According to the polarity of ion, electronics or hole (ionic acceptor or alms giver) will introduce polymer surfaces state, thereby make polymer surfaces charged.Conventionally utilize metal discharge pin or the string silk that tip curvature radius is very little to add after high direct voltage, near air corona pin or string silk end produces local corona discharge, thereby the real charge that the deposition of the dielectric surface under pin end is identical with spray point polarity, energy state generation electron exchange by the electro-ionic energy state in the string of deposits and sample surfaces shifts, and makes micropore piezo-electric electret thin film charged.
