Study on the Electrostatic Electrification of Polymer Packaging Materials

The rules of electrostatic electrification during contacting and parting between solids of polymer packaging materials were studied.The function of friction in the electrostatic electrification of polymer was analyzed.Electrification means were explained in detail,including stripping electrification,crack electrification,piezoelectric electrification,inductive electrification and attaching electrification.It's pointed out that designing more mature model and introducing more reasonable parameters will be the research tendency of electrostatic electrification theory.
